i just recently got 5 baby chicks. i've only had them for almost a week, but there are two that are growing combs already and 3 of them that are not quite yet. i am planning to build a coop for them this weekend (if possible), but i am not aloud to have roosters in town, and i don't want to build my coop for 5 if two of them end up to be roosters or whatever the number may be. i also don't want to wait 3+ weeks to build there coop. if that makes sense. so how do i tell if they are females or males? do i really have to wait 3 weeks to tell the gender? any help is much appreciated! thank you all so much!!
