How to Store Animal Feed Properly in Canada: Prevent Mould, Moisture, Pests & Waste

Buying quality animal feed is an important part of keeping livestock, poultry, and pets healthy. But what happens to that feed after you bring it home?

Improper storage can expose animal feed to moisture, mould, rodents, insects, and other contaminants. These problems can lead to unnecessary waste, higher feeding costs, and potential animal health risks.

For farmers and backyard animal owners in Ontario, changing temperatures, humid summers, rainy seasons, and freezing winters can make proper animal feed storage especially important.

Whether you're storing chicken feed, horse feed, goat feed, rabbit pellets, or livestock grain, a few practical precautions can help protect your investment.

In this guide, Chatham Farm Feed & Supplies explains how to store animal feed in Canada, choose suitable containers, recognize warning signs of spoilage, and keep feed fresh for longer.

Why Proper Animal Feed Storage Matters

Animal feed is designed to deliver specific nutrients to the animals consuming it.

However, poor storage conditions can compromise its quality and safety.

Common feed storage problems include:

• Moisture entering opened feed bags

• Rodents chewing through packaging

• Insects contaminating stored grain

• Mould developing in damp feed

• Exposure to direct sunlight and excessive heat

• Feed becoming contaminated by chemicals, dirt, or other materials

• Older feed remaining unused behind newly purchased bags

  
  

These problems can affect commercial farms and small backyard operations alike.

A clean, dry, organized storage space helps reduce contamination risks and makes feeding routines easier to manage.

Keep Animal Feed Dry and Protected From Moisture

Moisture control is one of the most important parts of storing animal feed safely.

When dry feed is exposed to excessive moisture, conditions may become favourable for mould growth and deterioration.

In Ontario, moisture can enter feed storage areas through:

• Leaking barn roofs

• Damp concrete floors

• Condensation inside storage buildings

• Humid summer air

• Rain or melting snow

• Wet feeding scoops and containers

  
  

Choose a location that remains dry and protected from weather.

Avoid leaving feed bags directly on damp concrete or outdoors under a tarp where condensation and water can accumulate.

Instead, place feed on clean, raised shelving or suitable pallets in a dry area.

For opened bags, use a clean, dry container with a secure lid where appropriate. Keep original product identification, feeding instructions, and lot information available.

Quick storage tip: Inspect the floor, walls, ceiling, and container lids regularly for signs of leaks or condensation.

Choose Suitable Animal Feed Storage Containers

The right container depends on the type and quantity of feed you're storing.

For backyard poultry owners or hobby farms, sturdy, clean containers can make daily feed handling more convenient.

Food-Grade Plastic Containers

Food-grade plastic bins designed for dry food storage can be useful for smaller quantities of animal feed.

Choose containers that are:

• Clean and completely dry

• Suitable for the intended feed

• Easy to open and clean

• Equipped with secure lids

• Large enough for the feed without overfilling

  
  

Be aware that some rodents can chew through plastic. Plastic bins may need additional protection in buildings with persistent rodent activity.

Metal Storage Bins

Well-fitted metal containers can provide better resistance to rodent chewing.

They can be useful for storing poultry feed, grain, and other dry feeds in barns or storage sheds.

Check lids, seams, and the condition of the container regularly. Keep containers away from condensation, rain, and extreme heat.

Original Feed Bags

Some unopened feed bags can be stored safely in their original packaging when manufacturer's instructions are followed.

Keep bags:

• Off the floor

• Protected from moisture

• Away from pests

• Out of direct sunlight

• Clearly labelled and organized

  
  

Never assume that an unopened bag is waterproof.

Prevent Mice, Rats, and Other Pests From Reaching Feed

Animal feed can attract rodents, birds, and insects.

Pests may damage bags, consume stored feed, or contaminate it with droppings, urine, and other materials.

To reduce these risks:

1. Keep feed containers securely closed.

2. Clean spilled feed promptly.

3. Inspect walls, doors, and storage areas for pest entry points.

4. Avoid leaving open feed bags overnight.

5. Check containers and packaging for damage.

6. Keep feed storage spaces clean and organized.

7. Store feed away from areas accessible to wild birds.

   
   

If you notice droppings, chew marks, damaged bags, or other evidence of contamination, isolate the affected feed and assess whether it must be discarded.

Never use feed known to be contaminated by rodent urine or droppings.

For serious pest problems, consult a qualified pest-control professional and ensure control measures cannot contaminate animal feed.

Store Chicken Feed Correctly

Backyard chicken owners often purchase complete feed in bags that may last several weeks, depending on flock size and consumption.

Common chicken feeds include:

• Chick starter

• Grower feed

• Layer pellets

• Layer crumble

• Broiler grower or finisher

• Scratch grain

  
  

These feeds should be stored carefully to protect their quality.

Keep complete chicken feed in a dry, secure location and use an appropriate container after opening.

Avoid allowing moisture to enter bags or feeders. Clean feeding equipment regularly and remove spoiled or contaminated material.

Importantly, keep different feed types properly identified. Chick starter, grower, and layer feed have different intended uses, so a storage mix-up can lead to feeding the wrong formula.

Protect Horse Feed, Goat Feed, and Livestock Feed

Different livestock feeds may contain grains, pellets, protein sources, vitamins, minerals, or other ingredients.

Proper storage matters across all species.

Horse Feed Storage

Store horse feed in a clean, dry, pest-protected area.

Keep grain and concentrated feeds clearly labelled and avoid mixing old and new products without considering their condition.

If a horse feed becomes wet, mouldy, or otherwise questionable, do not feed it until its safety has been professionally assessed.

Hay also needs appropriate storage and ventilation. Excessively moist hay can develop mould and may create a fire hazard through heating.

Goat and Sheep Feed Storage

Keep goat feed, sheep feed, and mineral supplements in separate, correctly labelled containers.

This is especially important because mineral formulations may differ between species.

For example, sheep are particularly sensitive to excessive copper. Do not treat goat and sheep mineral products as interchangeable.

Cattle Feed Storage

Protect cattle feed and grain from water, pests, spoilage, and contamination.

For larger-scale feed storage, regularly inspect bins, covers, unloading points, and surrounding areas.

Stored silage, high-moisture grain, and other wet feeds require different management practices from dry bagged feed.

Follow the guidance appropriate to each product and your feeding system.

Rotate Feed Using the First-In, First-Out Method

One of the simplest ways to reduce feed waste is to use older suitable stock before opening newer bags.

This is often called the first-in, first-out (FIFO) method.

For example, if you purchase two bags of chicken feed in October and another two in November, arrange the bags so the older, still-suitable product is used first.

To make feed rotation easier:

• Record purchase or delivery dates.

• Retain original lot and best-before information.

• Organize bags by feed type.

• Check product condition before use.

• Avoid mixing unidentified old feed into fresh feed.

• Follow manufacturer storage and shelf-life recommendations.

  
  

FIFO helps organize inventory, but it does not make expired, damaged, or contaminated feed safe.

How Long Can Animal Feed Be Stored?

There is no single storage period suitable for every type of animal feed.

Shelf life depends on factors such as:

• Feed ingredients

• Processing method

• Packaging

• Storage temperature

• Humidity

• Whether the bag has been opened

• Manufacturer recommendations

  
  

Some products are more sensitive to deterioration than others, particularly feeds containing certain fats or other ingredients that may lose quality over time.

Always check the manufacturer's label, best-before guidance, and storage instructions rather than relying on a universal number of weeks or months.

Purchase quantities that suit your animals' actual consumption and your storage capacity.

How to Tell if Animal Feed Has Gone Bad

Inspect animal feed regularly, especially when opening a new bag or using feed that has been stored for an extended period.

Potential warning signs include:

• Visible mould

• Unusual musty, sour, or rancid odours

• Damp or unexpectedly clumped feed

• Evidence of insects

• Rodent droppings or damaged packaging

• Unexpected changes in colour or texture

• Water damage to feed bags

  
  

However, not all contaminated feed shows visible signs.

Some moulds produce substances called mycotoxins, which can cause animal health problems. Mycotoxins may be present even when mould is not obvious.

Do not feed visibly mouldy or clearly contaminated feed to livestock or pets.

Do not assume that drying, removing visible mould, or mixing suspect feed with fresh feed makes it safe.

Animal Feed Storage Tips for Ontario Winters

Winter creates additional feed-storage challenges for Canadian farms.

Cold temperatures alone do not necessarily damage every type of dry feed, but temperature changes and condensation can introduce moisture.

A bag moved repeatedly between a cold shed and a warmer building may experience changing conditions that deserve attention.

To protect feed during winter:

• Inspect storage areas before heavy snowfall.

• Check roofs and walls for water entry.

• Prevent melting snow from reaching feed bags.

• Keep storage containers closed and dry.

• Watch for condensation in poorly ventilated spaces.

• Plan purchases around weather and available storage capacity.

Common Animal Feed Storage Mistakes to Avoid

Even experienced animal owners can overlook small storage problems.

Some of the most common mistakes include:

Leaving bags on the barn floor: Damp concrete and accidental spills can expose packaging to moisture.

Using previously contaminated containers: Containers should be suitable for animal feed and thoroughly cleaned and dried before refilling.

Ignoring older bags: Feed forgotten behind newer inventory may deteriorate before it is used.

Mixing different species' feeds: Feed formulations are not necessarily interchangeable between animals.

Leaving bags open: Open packaging can increase exposure to moisture, insects, and rodents.

Buying more feed than can be stored safely: Bulk purchases are only economical if storage conditions protect product quality.

Correcting these habits can make your feed storage area cleaner, safer, and easier to manage.

FAQA? bout Animal Feed Storage

What is the best way to store animal feed?

Store dry animal feed in a clean, cool, dry, pest-protected location. Use suitable containers or intact original packaging, follow manufacturer instructions, and inspect feed regularly.

Can I store chicken feed in a plastic container?

Yes, a clean, dry, food-grade container suitable for feed can be practical for chicken feed. Choose a secure lid and protect the container from rodents, moisture, and heat.

Retain the original feed label and lot details.

Can animal feed go mouldy in winter?

Yes. Mould can become a problem when moisture enters the feed, including through leaks or condensation. Cold weather does not eliminate the need for dry storage.

Should animal feed bags be stored on concrete?

Keeping bags directly on concrete is generally best avoided, particularly where moisture may be present. Raised shelving or clean pallets can help separate bags from damp surfaces.

Is mouldy feed safe if the mould is removed?

No. Removing visible mould does not guarantee that feed is safe. Potential toxins or contamination may remain. Seek qualified advice rather than attempting to salvage clearly contaminated feed.

How can I stop mice from getting into livestock feed?

Use secure, rodent-resistant containers, clean spills, seal access points, and inspect the storage area regularly. Address persistent infestations through appropriate pest-control measures.

Can I store horse feed and chicken feed together?

Separate, clearly labelled containers can be kept in the same appropriate storage area, provided contamination and accidental feeding errors are prevented. Never mix different species' formulas.
