They are all beautiful. It looks as though both roosters only have 4 points. They should have 5. I cannot see their feet so I cannot comment on them. They should be yellow or at least the bottoms all yellow. I think I like the shape of the 2nd roo better than the first but it may just be the picture. It is also hard to judge overall size on the pic.
The black hens look nice. However, I see a couple pretty large combs. I prefer the smaller ones. Again, it is really hard to tell in pics.
Your birds are very nice. I would enter them into a local show to start and see how they do. Talk to the judge afterwards and ask their opinion, usually they will talk to you. You can learn alot this way. By the way, where did you get your birds from?
