Hello everyone. I posted a thread a week or so ago about one of my hens that had lost all the feathers on her bum. I am writing now because, within 2 days, ALL 6 of them have lost their bum feathers. I have no idea what's going on. I have checked for mites at night but of course I don't know exactly what I'm looking for.. Just crawly little bugs. I haven't seen any blood drawn on the bums but a few of them have a significant amount of red skin (it has been very cold here in New England for a couple days) so last night I applied some Blue-Kote to the red areas to try to limit attention to the ares. This morning I let them out and most of them have blue beaks!! Did the blue stuff bother them,so they were picking at it themselves, or do I have a whole flock of feather pickers? Or bugs? AHHHH Here are the bums, pre-blue stuff. Any help or advice would be greatly appreciated.
