Please help! Seems I have feather eaters in my flock. I first noticed one of my girls with chewed feathers, she looks pretty ratty. Yesterday another turned up looking the same, chewed and ratty. I saw 4 girls go after her and take chunks of feathers from her back, including the first victim. I have 7 girls total. This morning I came down to find her looking like this :-(( so far I added black oil sunflower seeds in case it's a protein thing and I opened up their run to let them free range today. I will be running out for some blu-kote to spray on her back. Other than that I need some advice please I feel awful for her.
