I have a 1 1/2 week old "mystery chick" I put with my broody hen (she already had 3 chicks, and seemed fine with the new one yesterday). When my husband went out to check on them this afternoon the chick had gotten out of the caged run (where the mom and babies were) and was running around the backyard with all the grown up chickens. My husband picked her up to put her back into the brooder with all the other chicks, and noticed she had a big wound on the back of her neck. I brought her in the house, and set her up in a box by herself with food and water. She is eating a drinking and pooping like normal. What else can I do for her. Is this something she can recover from? You can't see it unless she streches her neck.
