Hey there. I got a new hen about 3 weeks ago. i have been introducing her to my other 3 hens. I put her in the coop because yesterday they all seemed fine together. This morning she has feathers missing on the back of her neck and blood from where they had pecked her. I have seperated them again but is there anything I can put on her wound to help her heal? I dont know why it is taking so long for them to accept her. I read before it only took about a week.
