I know how you feel only I didn't overbuy enough. I got 7 "sexed" pullet EEs hoping to make sure we got 4 egg layers. Ended up with 2 pullets out of the bunch.I feel your pain. I'm super paranoid about my last frizzle from them turning out to be a rooster too. I check that comb daily.
Also, when do wattles on females come in? My frizzle is getting them now and they're bright red. She is only 7 weeks. Something to be concerned about or is that normal for cochin hens? The comb is still small (nearly hidden by those curly feathers).
I'll take some pictures later if I can, but she's difficult to get nice photos of.
Suddenly buying those three extra chicks doesn't seem like it was such a bad idea, considering of the 8 chicks I have 2 are definite roosters... At least on is pint sized. He can hardly be considered a chicken at this point.

Was hoping to be done with the brooder, but I got 4 more "Ameraucanas" from Cal ranch hoping they are pullets like they say. The kids want blue eggs! I know they are EEs and not AMs.

It's a rude awakening to post pictures of your first Ameraucanas only to have 14 poeple tell you that you have EEs.
It is good to know though and everyone is really nice about breaking it to you. Then you get a real education on Ameraucanas and a whole new respect for the breed.
