Back in May I posted pics of my girls behinds and back where they were missing all of their feathers. Well they are still missing them. And I really don't know what else to do. I have no where to keep them separated from the ones that aren't missing any. Which is less than half of them. I have 49 total and more than half missing them. They act ok. Not sick. I have a few that are now starting to molt too. I put vinegar in their water every day and oil of oregano too. They get probiotics couple times a week. I am just so clueless and I feel helpless too. They don't have any mites. I live outside of New Orleans and we have had a very unusual even hotter than normal summer and the rain. Oh my that has been really bad. They have a fan and air conditioning in their coop. I clean it once a week. Any any ideas please help me.
