Its a little hard to tell from the pic but the little spike on the hens comb is coming from a little indention that just looks kinda like a shadow in the pic.
I'm afraid I already know the answer but do the last 2 blrws have inverted combs? What about the first 1? It isn't inverted I don't think but is it acceptable? I really don't want to cull more birds from my small flock but don't want to breed birds with such obvious faults even though they are very nice otherwise. I have already culled a hen with incomplete lacing & 3 roosters with light hackles from my young flock of 13.
