I hatched some chick and two of them are deformed. One has a leg that it drags behind it. The other has a swollen neck and a foot that is sort of turned backwards. My wife said that the neck wasn't swollen when it hatched. There was about three hours between then and the time I got home. The swollen one keeps chirping and sounds strong. Is it suffering or a sign that it is fighting? I don't want it to suffer, but want to give it a chance. I need advice.
