I think I may see a longish curly sickle feather. If I am seeing things, and it's not there, then my vote is pullet. But if that long tail feather is there, I say boy all the way. Black and white EE's are so hard!
I have 10 Buff Orps and four of them are roosters. I have 22 three week olds in the brooder but the are supposed to be sexed pullets. Then I have 16 eggs in the incubator.
Yeah, there is absolutely no way that is a hen with that tail. That is really quite unfortunate, he is really pretty. Were they straight run from a hatchery? I've heard that sometimes hatcheries just send a bunch of roosters as straight run...
Christina is an awesome name for a rooster. I had a production RIR named Tallulah because I didn't know he was a rooster (he came from a "pullets" bin) til I saw him crowing, and even when I started hearing crowing I thought it was my Buff Brahma cockerel. He definitely wasn't a pullet, and I have his two sons who look just like him as proof!
