I have a 10 month old ISA brown that I found today that just stands hunched with her tail down. She can stand, but after a while just lays down. I checked for lice/mites, foot injury, and everything seems okay and nothing out of the blue. I read up on egg bound so I gave her an Epsom salt bath. When I examined her, nothing seemed unusual. I gave her an egg and she’s separated from the rest. Is there anything else I should do? I’m worried about her and don’t know what’s wrong.
