The feathers have dark shafts. I don't think there is a standard color variety that fits. It's a pretty bird, but I think it is a cockerel with that amount of comb so early.
Yes, the last one has a pea comb, so is an Easter egger. Not all of them have beards. Yours is a pullet.
The red one has a rose comb, so can't be a Buckeye. It is a Cinnamon Queen pullet. CQs are a sex linked cross of a red rooster over silver laced Wyandotte hen.
I think the first two are Cinnamon Queens, and the last is either a Sicilian Buttercup or some kind of Easter egger. A close up of its comb would help determine which.
It could be a starlight green egger, but I still think hatchery quality gold Campine because of the huge comb. I know of a couple of hatcheries that list them.
I think it probably is a blue Marans or blue olive egger. Black skin on the face and comb happens sometimes with many blue and black varieties, and often it fades away as they mature.
You can check under the feathers to see if the skin on her body is also black, but I suspect it will be white...
Both fit well for Starlight Green eggers, although the white and brown one could be an ISA brown. Egg color will probably be a determining factor, but that's a long way off.
I'm not sure what you mean by the gold cream coloring for roosters. You have a flock of different breeds, so the chicks will vary in color depending on the parents involved.
An egg eating rooster? That is unusual. You could try putting fake eggs in the nests to see if that helps, or housing him...
I agree. The buff Chantecler is the buff colored on, the Welsumer is darker brown, the Bielefelder is brown with some gray in it, and the black and white is the mottled Java.
