Could someone please tell me the difference in looks from the Rhode Islands and New Hampshires? I have ten of each and they are 12 weeks old. One set has large red combs and dark tail feathers. The other set has smaller combs and dark tails. I've looked on feathersite and don't see any visible difference between the two. My daughter is showing a set of pullet and cockeral for her 4H project tomorrow. Thanks for your help.
