Please help, somebody. We hatched out three chicks about a month ago. One died this morning while I was not present. The other two are in a brooder, Phoenix the broody mama hen is showing no interest so she is not with them. They have a heat lamp. One chicks beak is chatering, has been all day. The chick that died did the same thing, but it's crop felt like it was full of water. We felt it and it felt bubbly, then we were not able to feel it again. I am worried that the same thing will happen to the others, and we don't want something spreading through our flock. Please help, we don't know what is happening. Nothing feels abnormal, everyone is eating drinking and pooping fine, but they stay fluffed up and don't right.
