One of them is def. a hen, we are getting an occasional egg. Honestly, I don't see a roo in the bunch, so if you do - please tell me what to look for. #1 has a huge round crest, #2 & 3 are smaller, but still roundish, and the blue has a small round crest. They are all about 20 weeks old. Nobody is crowing, yet. None of the crests are 'spikey' like the mohawks I've seen. Thanks for all input!
