Large Marge never lost her balloon butt or laid an egg (unless the soft-shelled egg that someone dropped from the roost a couple of mornings ago was hers), but her color did come back to her comb and wattles. My concern is that the skin on her backside is rosy PINK today, and she has either some irritation in her skin or something on her side near her tail- I don't know if it's where she got plucked by the other hens or what. She still eats and drinks and poops, and she still lingers in the hen house in the mornings unless she hears me bringing treats. She acted sick last week, but she seemed to be a bit better (except for her rosy pink butt now and no eggs). I've soaked her in warm water, massaged her abdomen gently, felt for an egg (never found one), and even tried to withdraw fluid in case it was ascites (no fluid ). Does anyone have any idea from the description and these pics what this could be? Does the change in her skin color indicate infection?
