the bantams are a little over 3 months old. i've had them at the last 2 swaps for sale, so i'm sure they're at least 3 if not going closer to 4months old. i think they are hens. they dont look like boys but i'm learning that i am not good at telling that all the time. i'll look closer at them and if i'm wrong i'll repost..i have to go convince a cow that it really wants to suck on a bottle right now.
