We have a little Black Copper Maran chick that has both pasty butt and constipation. She is having a lot of trouble pooping and makes pained squeaks when she does. On top of that, her poop has been sticking to her butt. We are soaking her in Epsom salt water hoping that helps, but if anyone has any information that could help, please by all means, do tell. It may be important to note that this particular chick is a runt among the others being only a half to a third the size of the others. I say again, if anyone can help that would be great. We would rally like to keep her.
