Can chickens eat bird food? It's a question you may be asking if you have a flock of feathered friends as part of your family.

The best bird food makes a delicious and nutritious snack for the wild birds that visit our gardens, but is it suitable for chickens? Well, according to expert vet Dr. Rebecca MacMillan, chickens can eat bird food in moderation.

That being said, it's important that bird food be considered a 'treat' item and not a part of your chickens daily diet. That's because it lacks the correct balance of nutrients chickens need to thrive.

Below, Dr. MacMillan explains more about this and also shares what food items you should never feed chickens and which foods are the healthiest and most nutritious for them. Let's take a look...

Can chickens eat bird food?

As you know, chickens will eat most things that they can get their beaks on, but that doesn't mean these foods are always good for them. When it comes to bird food, Dr. MacMillan says these mixes are okay to feed chickens as a treat, but you want to avoid dishing this up on a regular basis.

"Chickens can eat bird food, including wild bird seed mix, but only in moderation," she says. "They shouldn’t eat it regularly as it does not contain the right balance of calcium and vitamins and can be too high in calories. This could be a particular problem for laying hens. It is not a long-term substitute for their normal chicken pellets, so must only be given as an occasional treat."

What should you not feed chickens?

While chickens can eat a variety of kitchen scraps, Dr. MacMillan says there are some that you should avoid.

"Uncooked potatoes and their peelings should not be fed to chickens as they can be quite high in solanine, as are green tomatoes. Solanine can cause neurological issues, digestive upset, and breathing problems," she explains.

"Uncooked rice is not suitable as it can swell and in the digestive tract, causing discomfort or even a blockage. Chocolate is potentially toxic to chickens, as it is in many other animals. Butter and cheese are too fatty for chickens to eat regularly, as are fried foods like chips.

You must never give them any food that is rotten or moldy either, as this could make them sick."

What is the best food to feed chickens?

When it comes to the best food to feed chickens, Dr. MacMillan says that commercial chicken feed will always be number one. "This will be the staple part of their diet and is formulated to meet most of their nutritional needs," she explains.

"Your chicken will also enjoy eating bugs as they scratch and peck around your yard. They will have a go at most things including grasshoppers, ants, caterpillars, slugs, and beetles. If your chicken isn’t free range, then you could provide them with dried mealworms or crickets instead.

Chickens will also enjoy tackling weeds such as dandelions and nettles, as well as the occasional kitchen scrap like cooked pasta, cooked rice, fruit, chopped nuts, and oats."
