Sister got her butt stitched up tonight. I can't say Thanks! enough to Dr. Chris, my army medic friend*. I brought him some info on how chicken's vents work (thanx BYCers) and he did a very careful exam of Sister. We were relieved to find there was no internal tearing and very little necrosis. He did a great job of matching up what parts went where and stitching them together. The stitching itself took about 40 minutes, a long time for Sister to be on her back, and he did use Lidocaine as per the UGA Poultry Science Department. But Sister did well and popped up as soon as I unwrapped and released her. She has drunk some water (with electrolites) since we got home. She did whip around and peck at her bum when she first got back in the hospital cage; I sure hope that was a one-time thing. She's quite swollen and the urates seem to drip out, but she did expell a poop normally. I've got to start her on antibiotics tomorrow. I've got oral Amoxicillin. Anybody know the correct dose? Couldn't get a decent 'after' pic of her vent. Will try again tomorrow. *No local vets will attend chickens. Dr. Chirs is a human GP who spent time in Iraq. There were no vets there so when an animal needed stitching, he did it. As he said, 'Tissue is tissue." Gosh, I hope this is the end of this situation (pun intended !
