We have one very, very tiny little easter egger chick that is 7 days old. All of my other chicks (that are 8-10 days old and different breeds) are at least twice the size of it. They all have wing feathers and the beginnings of a tail and shoulder feathers and the little EE baby hasn't sprouted any yet. It seems to be making it's way otherwise, but I can't help but worry - In the beginning it was very unsteady and had pasty butt, but we got that cleared up. It's back end just seems so tiny but I don't know if it was a lack of feathers compared to the other ones.
