I have a 4-10 hatched Green Queen too! Supposed to be a pullet, which I believe she is. Pale comb, doesn’t crow (yet). But she’s the biggest of our 8 chicks, too.
We have Wyandottes, two silvers and a golden. Our golden is a little pain and pecks at us a lot. But the silvers are just as docile and sweet as can be. They’re good layers, too.
