Cooked porridge becomes sticky and can harden around a bird’s bill, blocking its ability to eat. Always serve oats uncooked.

How to Serve Oats

Scatter on the ground - The simplest method. Good for ground feeders like doves, sparrows, and blackbirds.

Mix into seed blends - Add oats to sunflower seeds, millet, and dried fruit for a varied feeder mix.

Make suet cakes - Mix 1 part suet or lard with 2 parts dry oats. Add dried fruit or chopped nuts. Let it set, then cut into blocks and place on a platform feeder or hang in a mesh bag.

What Types of Oats Work?

Rolled oats - Best all-round choice. Easy for birds to eat.

Steel-cut oats - Fine, but harder for small birds.

Oat bran - Good mixed into suet cakes.

Instant oats - Acceptable but tend to be dusty.

Oats soaked in milk - Never. Dairy is harmful to birds.
