they eat small stones called grit - it turns into the shell on their eggs.
in the wild birds would eat the shell on unwanted eggs to create new ones.
They eat rocks to cut up the food they eat with rocks they save in their throat. That's what i learned. (I'm 11 years.)
Chickens
Actually, chickens are very opportunistic feeders like most birds. Birds that are specifically seed eaters will not typically eat animals; however, consider the vast variety of birds that eat suet. Chickens will eat anything practically. In fact it used to be a common practice at poultry farms to toss the carcasses of dead chickens into the feed bin. It was considered a bit of free protein that the other chickens did not seem to mind. Yes, chickens are even cannibalistic.
NO, what are you on..? chickens can't eat strawberries.
Birds and chickens eat ticks.
They eat baby animals such as chickens and birds and any other small animal- even cats.
no, an eagle does not eat chickens as it is a type of chicken
no,not necessary that all birds do the same...
Not a good idea Chickens are aggressive with other birds, they are also opportunistic omnivores which means they will kill and eat the smaller birds if they get the chance. Given the size of the chicken verses the size of the canary i would be wary about housing them in the same living area.
Raccoons do eat birds, including birds people keep for pets.My daughter has baby chickens. Raccoons killed and ate three of her chickens, so yes, they do eat birds.
Foxes will eat any bird they can catch but this is usually limited to ground nesting birds.
Chickens are omnivores and can eat almost anything. It is a myth that they only eat grains and commercial feed. They love fish and other proteins. Never feed your birds spoiled meat as it can make them sick.
