Kathy,
I assume all are the same age.
Pic one, he is looking good, watch the tail, if it doesn't fill out, don't use him as primary breeder. He does have a nice head and comb as best as I can tell from that pic.
Pic two, if he keeps the head that low all the time and the breast hangs down, cull him. Otherwise a better pic is needed. If he normally stands tall, he is looking good. I'd like a better pic of him more at ease.....
Pic three, if his tail doesn't pic up or his top line doesn't get any better cull him also. He has a small head leaning toward the crow head.
Pic 4, good width, but looks like he drags his breast, unless he is running away. Probably need a better pic of him at resting. Looks like a small head and tail is low.
Pic 5, he is looking good, His top line is about right, the new primarys are probably making his wings tender and making his wings hang low, nice tail, I'd watch this one.
Pic 6, He looks ok, but you have two other birds that look better.
Pic 7 Only thing I can really tell here is the closest bird is looking good and I'd like to see the farthest bird more at ease. If he raises his tail, he is nice.
That is a good hen, you need to mate her with a lighter colored rooster or else her progeny will be darker, hens carry two coloring genes, so you are fighting the dark pigmentation gene with her anyway.
Overall, I'd say you got a good start, it took me hatching 180 birds the first year to get 2-3 like you got, so the genes are concentrating now and the progeny are getting more like the parents. Don't fret about the variation, like I told you, they were a mess when I got them and they have come a long way. Also, large combs mean more hormones, that is what you want. Large heads also mean large body structure, so look for those.
How did I do? Did I pick any of mine as keepers?
