Hi I have to baby Welsummer chicks, both hens supposedly. They were born on March 16th 2016. They never have had a problem with eachother but I woke up one morning to see that my baby Poppy had a huge bloody hole on the back of her head. I've been dabbing warm water and putting neosporin on it but she keeps scratching and it's making it worse. I want to cry everytime I see it. I figured her sister peaches was attacking her "pecking order" but I kept a close eye on them and she isn't attacking her at all? I even tried to separate them but she flew out of the new box and got right back into the brooder with her injured sister. I'm not sure what to do but I hate the sight of this. I feel so horrible. Will she die?
