I have a Bantam Buttercup and a Bantam Blue Laced Red Wyandotte. They are both 3 1/2 weeks old. I've heard Buttercups can be sexed by their color. Both of these are feathering in slowly. I have another Bantam Wyandotte that I think is a girl and she has a lot more feathers. I need your best guesses because I need to get rid of all my cockerels tomorrow. Buttercup's Comb Wyandottes' Comb Please give me your best guesses!
