I do understand why you would be confused. I have a 12 week wyandotte bantam that looks just like yours, same color too. Looks kind of like a boy but acts like a girl, well mine has never tried to crow. According to Henderson's chart they are supposed to be moderately early maturing but I have a Jap bantam that crowed at 5 weeks, and OEGB(RIP Ashley) that crowed at 8 and 2 silkie roos that crowed at 9/10 weeks, all of these from the same group. I am waiting for an egg or a crow before I commit to calling Madison a him or her.
