I think size wise they're all over the place. I have hatch mate hens and one is maybe 3 1/2 and the other one is easily over 4 1/2. The larger one has the light eyes white earlobes and dark green legs the smaller one has dark eyes red earlobes and light green legs. Their brother from the hatch has light eyes white earlobes and light green legs and is dumb as a rock. They must be realllllly inbred.
