My first hatched chick "Myra" seems to be having a problem. This little one has a really big rear end. It appears swollen. It took a lime green poop in the bator. My immediate thought was pasty butt, but pasted shut by the egg yolk because it had a lot of dried slime on it after hatching. It's like it's butt is so heavy that it can't walk. Here's a pic of it rolled on it's back. I think it closed it's eye for the flash. And here it is on it's belly, propped on it's butt with it's legs out in front of it. I know someone here will know exactly what is going on with this chick. Is there something I can do? I gave it a couple of sips of polyvisol already, and I've given it a chicky sitz bath. What else can I do?
