Sounds like your little roos are a straight comb and a pea comb. To keep from getting another roo, I'd stear clear of any that are getting black feathers in their bodies. Checking comb size doesn't always work with American Gamefowl since a pea comb rooster will seem to have a smaller comb than a straight comb pullet will. Old english only come straight comb, since you are seeing pea combs in the ones you have I would bet they are American Games. The hens will be the best incubator/brooders that you will ever own. The colors and personalities in these birds make them a blast to raise, even though they may take a little extra care when it comes to penning them. You might want to do a little research on the various color patterns of gamefowl so that you can familiarize yourself with what to look for as per hens. Good luck with your little birds and post us some more pics as they grow older...
