I have four girls, all about 20 weeks. My Ameraucana attacked my Brahma last week - first time I've encountered this. A little blood and many lost feathers - but she will be OK. I came home today to find a severe attack on my sweet Lavender Orpington, Lucy. I am at a loss for words. I know the very basics of chicken wound care... but would appreciate any advice on how to best help Lucy. At what point do I need a to see a vet?
