I don't know much about chickens since I'm rather new and guessing it's way too early to know sex. I'm suppose to have all pullets but we know how that goes. I know for sure my EE and BA are 2.5 weeks old and I *though* my gold Sexlink was just a few days older since the feed store got a shipment in a couple days earlier. My sex link is by far the largest and has a much bigger comb. Should I be concerned or is it just the breed and being a few days older? Or do y'all think she is older than 3 weeks? In due time I will know for sure but I was just hoping someone with some experience would have some insight.
