One of my chickens got plucked by a hawk! I figured out it was happening because two of our hens were at our backdoor, frantically clucking to come in. When I looked outside I saw a huge hawk -- we think a red-tailed-- hunched over one of our hens, and an enormous pile of feathers! (We live in Brooklyn, NY, so this is so shocking for us!) I assumed she was already a goner, but when I went outside, the hawk flew off and the hen jumped up and ran and hid. Even then I figured she probably had serious injuries. But when we finally got her into the coop, she appeared okay. I could see scrapes on her bare skin, and she was holding one foot off the ground, but still walking on it. I seriously think our brahmas are so fluffy that the hawk couldn't find the meat under all those feathers! It's been a week now and she is absolutely okay -- she even laid an egg the next morning! But we've been lucky with the mild weather this last week, and I'm worried about when the cold comes back. She has big patches of bare skin (and is missing most of her wing feathers on one side). How long do feathers take to grow back?
