I have questions about gender on 13 chickens of all different ages. This first one is about 14 - 15 weeks old I think it is a roo my hubby thinks it is a hen. It is the same age as the BR and he crows alot and has been for awhile now but the Lt. Brahma hasn't yet. Also I would like to know is why this Brahma's legs are yellow and my hens legs are white. Next are two that I hatched out on mothers day so they are about 7 weeks old. I know the breed just wondering about the gender. These are 10 chicks that I bought at a flea market they are almost 5 weeks old 5 are Polish, 3 are Lt. Brahmas and 2 are unknown. Wondering about gender on all. Here are the Brahmas Here are the two unknown And one group pic Thanks in advance for your help.
