They are just looking for food! I had a cockerel that fell off the chicken truck on the way to be slaughtered. He was just laying in the middle of the highway. Many of his cage mates were dead. I had to teach him how to walk and eat and drink properly since he lived crammed in with others in a tiny cage with no movement. I didn't even know what a meat bird was back then. Can't remember how long he lived, but his legs gave out and I had him euthanized. Your chicks are having a wonderful life compared to my poor Frank. They are not designed to live long, so just help them have the best time for the short while they are here. And eat them and be grateful. Don't let their lives be wasted.
LOL They have full bellys and ignore the food dish to try and be with me.
