I ordered 10 Welsummers (available as str. run only) and 5 BO pullets from Cackle on July 1. They arrived yesterday, all alive with one extra Welsummer. I had read that Welsummers are sexable by the color pattern on the back of the head/neck. I do have some that are clearly pullets with the well-defined stripe and some that are clearly cockerels with the "blurred" stripe. But there are a few that I'm having a real hard time deciding on because they are somewhere in between. I tried to get pics of the back of their heads but they didn't come out well. I guess I'll just have to wait and be suprised!
