My 16 month old Buff Orph (Sunny) is oozing from her vent; at first I thought she had broken an egg internally, but that was over two weeks ago. Now it looks like diarrhea, green & white liquid. It's constant. She has become very thin, but continues to eat & drink, peck, scratch. The worst part is she stinks-BAD! I have been feeding her some yogurt and even soaked her bottom. None of my other five girls appear to be affected. Recently, she will stop and strain to poop and makes squawking sounds. Could she be constipated? I would really appreciate any kind of help, I would hate to lose her.
