Okay, so I've read a bit about this odd symptom a few places here so I know that others have had the same experience...but I haven't been able to find any solid answers. My year old hen seems normal otherwise. Eating, pooping, doing her usual daily activities with her flock, and laying eggs as far as I know. May be molting since her head has a few bald spots too. Just wondering what's up with the bald squishy bulge under her vent. Her vent looks normal. I felt the bulge pretty well and there is nothing hard in there and she didn't seem to mind it being handled. I read about sticking a needle in there to try and draw out the fluid, but I'd rather not. Tried to get a photo, but wiggly hen in one had and camera in the other made for very unhelpful shots.
