Our girl Lucy (easter egger) is losing feathers. She is 2.5 years old. The feathers she's losing don't have the feather shaft or fluff above it attached. The feathers are from the back of her neck. I don't think it's from being pecked. I've seen them just fall off of her. She seems to have lost some of the fullness of her beard & muffs. Some of it is probably stress. It's getting hot here. Also, we had to have our other easter egger, Dirty Birdie, put to sleep a couple of weeks ago. They'd been together since they were day-old chicks. Lucy followed her everywhere. Lucy also has constantly poopy feathers below her vent. She doesn't seem to position herself at much of an angle when she goes and her feathers seem to grow up at more of an angle in that area than our other girls. Could that be the problem? We've trimmed the fluff, but that has just caused the poop to get stuck in the feathers directly below the vent. They were all given dose #1 of Valbazen a couple of days ago. Absolutely no signs of lice or mites on any of them.
