Hi everyone, I am new to this community and just started raising my own baby chicks 3 weeks ago. While my wife and I are excited with this new endeavor, I suspect one of my baby chicks (a white leghorn) is a rooster as he/she is already developing a comb. I read on this forum that it is more common for white leghorn to develop comb earlier but i'm still very concern. The other 2 chicks (Australorp and Americauna) don't have any comb development at all. Can any experts in this community help me out? Our city will not allow a rooster and i can't afford to wait 6 months to find out one day when (he) starts to sing! I am attaching a few pics here for reference, perhaps some experienced chicken owners can differentiate better?
