In my opinion, this will be a cockerel. Looks just like my cockerels. :)
The other one def looks like a pullet.
Here is my pullet in front, with the boys.
Hmmm, I was thinking the one Black Copper Marans (on the left in the pic) might be a pullet too. You don't think so?
The good news for me is, the breeder wants a couple of roosters, so is willing to exchange 2 for pullets. :)
