Bev here. I've been reading posts recently but now I need help. I have 5 banttys. Lost 1 2 had poop stuck last night. I did clean it as I read elsewhere it's called pasty butt. 1 this am is lethargic very light weightweak eyes closed but still peeping. Does not eat. It had purple around the vent bulging. Heat lamp has helped her stand. Plz what to do? Thanx!
