We just hatched 17 bantams and 1 of them isn't fluffing up right and her eyes are swollen (they can open, but not easily). She did have the top 1/2 of the shell stuck to her at one point - a bit sticky overall. I gently washed her off and she seems to be fluffing a little now. But still not opening her eyes much and complaining a lot. Gets on her feet ok. Any ideas what else I can do for her?
