I have pea chicks that hatched this past weekend. One of the chicks stomach seems to be very swollen/bloated. I checked for pasty bottom and it is fine and the chick is "going" (at least it did when I was trying to check its bottom. Still, I soaked it's little bottom in warm water to see if it helped. It is also quite listless. Any ideas??? I am freaking out about it. Thanks!
