Same problem here: Bald, puffy, red butt. Vent is not protruding. She's eating and pooping. She is acting "normal." I mean "typical" of a chicken. She's been like this sans the red part with bald puffy butt for 6 months?? And carries on like normal. I've red multiple threads and no one...
I'm still around too. As a child I remember running in the "bug man's fog." I'm glad I didn't drop dead that day, but I don't know what I did and kinda wish I 'didn't.' Respectfully, do you know what I am saying? Preventative poison? Thinking I'd wait the 7 days...and I wouldn't sell them either.
