Hello! I am a newbie in the chicken keeping world and need some help. I have 11 chicks that are 3 weeks old, I have 3 Hubbard golden comets, 3 tetra tints, 2 buff orpingtons, 2 Easter eggers and 1 black australorp. They are still in their brooder for now and are growing and doing really well, all except for the 1 black australorp. For the past week she has been anti social with the other chicks and I haven't actually witnessed her eating like I have the others. Granted I am not down there with them constantly, but the other chicks will mingle and go about their business with me sitting there and "Delia" will not. She stands in the corner by herself all puffed up with her eyes closed. I have no idea what could be wrong with her. Today when I was down with them I did see one of the other chicks pecking her a little, I know they have a pecking order so is "Delia" just at the bottom of it or should I be more concerned? Has anyone had a similar situation? She is also the only chick that won't come to me when I sit down and call them over.
