I have 11 chicks in the brooder. One chick seems to always be by itself. Is usually the last to eat, the first to sleep, and when all the other chicks are dog piled on one end, this little one is at the other end of the brooder alone. The chick is a Polish(white or buff laced, not sure yet) it is smaller than the rest and while the other 10 chicks have most wing feathers and at least a half inch tail, this one has about half it's feathers and just started sprouting a little tail. I am concerned about this little chick. I haven't seen the others being mean to it or pecking it much.(no more than they peck each other) Should I be concerned or just keep watching?
