Here is some of my girls. I have 9 total. 3 are from mypetchicken.com and they are tiny and very little copper. The rest are from the same local breeder as my boys. There are a couple with nice combs. Just not in this pic. Their coloring is great though!View attachment 1123673
definitely keep 2 boys. I have a hen with such comb and the boys I got from her are culls due to s-shape combs. I hope the girls will not inherit her comb. at the moment they look ok but they are still too young.
your boys don't have great combs but at least they are acceptable.
again, @Chooks man will tell you better.
