First time raising chickens. They are now 7 weeks old. Incubated, so should be a pretty even split on gender. I am assuming the comb should be able to to tell me at this point the gender. Some are becoming a lot more prominent, and others are staying pretty flat. This is mostly now just for curiosity, as I plan on keeping the hens and butchering all but 1-2 roosters. I'll wait a couple of months. Thanks.
