Purchased 15 RIR pullets last week, all seem really healthy. One of the chicks is not developing its feathers like the others. All the other chicks have most of their wing feathers and their tail feathers are about an inch long. The one chick is the same size as the others, but it only has about a half inch of it's wing feathers and no tail feathers. Is this something that will solve itself over time or should I be doing or giving this chick some kind of special attention? This chick seems to be somewhat of a bully, pushing the others out of the way for it's food and water. There are others that are a tad smaller, but they are developing at a much faster rate.
