Thanks for the response. What am I looking for as far as their comb and crest to sex them? Will their comb be larger for a roo? It is so minimal to start with. Also, will the roo feathers be glossier? the blacks look that way, but I can't tell on the whites. We wanted more but they did not hatch. We started with 18 eggs, three hatched, one never grew and didn't make it a week, the second developed wry neck and didn't recover. So, we have one tiny fluff ball in with Favorelles, Houdans and Araucanas. You know how chicken math is.
