One of my Buff Orpingtons has a couple of problems and I'm looking for advice. Sorry about the kind of gross chicken butt photo in advance. Problem #1 - Developed a white discharge from vent and redness under vent this summer. Continued laying till about a week ago Have treated with baths to clean the area, treated vent and irritated skin with anti-fungal cream and triple anti-biotic oinment. Have isolated her from other hens and given water with ACV, also given 1/2 to 1tsp. greek yogurt mixed with oats per day. Also tried espom salt flush 3 days in a row - 1 tsp. espom salt in 1 oz water orally with baby medicine syringe. Problem #2 - Missing feathers on her back. She's been our rooster's favorite hen since day 1 and has never had many feathers on her back as a result. I've worried from time to time if this was maybe some parasite instead, but have checked and never seen anything. Being removed from the other hens she has started to get the beginnings of feathers on her back. I've put a hen apron on her, so hopefully this will help. Not sure what will happen when we take the hen apron off though. Does anyone have any ideas about preventing treading? In spite of these problems she is perky & normal - thanks for any advice!
