Hi, I'm brand new to raising chickens. I hatched these chickens ~10 weeks ago. Can you help me determine their gender? I'm focusing on determining the Ameracaunas' genders first. They are mostly white with some black and are centered in the first 3 pictures. If you can help with the gender of the other chickens pictured -- that'd be great as well. I can also post additional pictures if needed. Thanks in advance!
