He's partly buff laced Polish for sure. But his comb and eye color are both wrong for purebred Polish, and his crest is too small. The other parent could be a Gold Sebright bantam, but there is no way to know for sure. He is very pretty!
Blue partridge, maybe? The red chick looks like it is mixed with blue also. It probably means the parents of these chicks were different colors, resulting in mixed coloring. That's not uncommon with Silkies.
Yes, they should all have head spots because they will all have at least one copy of the barring gene. But the spots sometimes don't show up well on certain chick fluff patterns. They can though. That's why I say there is no way to tell gender on these yet.
Since the father is double barred, all of his offspring will have at least one barring gene. It may or may not show up as a head spot on striped chick down. Really only pure Legbars can be sexed according to the usual autosexing methods, but I don't see any way at this stage to tell the pure...
It looks to be a buff Wyandotte. I think it's unlikely that there is an old European breed with yellow legs, buff coloring and a cushion comb. Maybe, but if so I don't know it.
I think it is too early for accurate guesses. Crested breeds take longer to tell. You can send in samples to a lab if you are impatient. Otherwise I think it's going to take a while.
Crested fowl take a long time to tell gender, so I don't think there is anyway to be certain at this point. But going by the rounded crests I am guessing they are pullets. Time is the ultimate judge.
If you are impatient it is possible to send feather samples to a lab. For a price they can tell...
Sorry for Goober. It's entirely possible buff Monorca was added later, but I don't think they were in the original crosses. I'm pretty sure buff Minorcas were developed after buff Orpingtons.
Black Minorcas were used for black Orpingtons, but black and buff Orps were created using different...
There's no way to know for sure about the rooster in the original post. It's just a guess on my part that game was involved in his mix, and I know it could be off, but that is my hunch.
Your rooster is handsome! I've never heard of Minorcas being involved in buff Orpington ancestry. The...
Opinions vary. To me the longish legs, body conformation, high carriage of the tail, and prominent breast, not to mention coloring, say game is in his mix somewhere.
