I'm no expert on CRs, but they look pretty good to me, Scott.
I have 5 chicks under Dottie on Day 19 that are out of Rex and his mother and aunts, including two of Dottie's own. This is the first breeding where I've tried close to what Bob Blosl suggested, though sadly, I could not do it with the late Indy, who had superior barring to Rex, who is obviously single factor barred, but a good size and overall form. I candled the eggs when Dottie went on her break and all five have chicks in the air cells so they should begin pipping by the end of the day, I'd think. If one comes out with Dellie coloring and/or pea comb and beard, I'll know that Scout, the Del x EE, got in a lucky shot, but Rex keeps close tabs on the BR hens and they are tough cases for a less-than-alpha male to get hold of, LOL.
