If it is that old, I would say it was a girl! Yea, true Ameraucanas are hard to some by. I was lucky enough to just hatch 2 wheaten Ameraucanas! Now to wait for months and months to get those nice blue eggs!
Roo....Already has large comb and wattles. My pullet frizzles are 13 weeks old and have no development. I can't see his legs, is he a cochin? Does he have feathered legs?
Frizzle is not a breed...it is a feather gene that makes them that way. A frizzle can be Polish, EE, Cochin, etc. I have some frizzled EEs and frizzled Naked necks and had some frizzle Polish, but the Polish were roos so had to rehome them.
Mad Maxine is EE X Polish frizzled. My Isbar...
They can start crowing at all ages. I had one roo that waited until he was 4 months. The roo I have now is crowing at 8 weeks and I have heard people swear theirs started crowing at 3 weeks! hahahha!
The top one was a Polish X Non Naked Neck frizzle. The bottom one is a Non Naked Neck frizzle. (The Non NNs came from Naked Neck X Easter Eggers) They will lay green eggs.
