I've been really lucky. There is a very big difference between the rate of feathering between my roos and pullets. I can usually tell in the first week or so. My girls sprout tails, and the boys don't get any tail feathers for 3 weeks or so. But maybe that's just my line? My boys also develop a three ridged comb by 3-4 weeks. Some of the girls will occasionally confuse me by getting pink combs, or maybe feather a little differently, but the tails are always totally different. That's not true for everyone's chickens though. You should post pictures.At what age can you tell a roo from a pullet?
I have three blue ameraucanas that are 7 weeks old. One holds itself taller and stretches it's neck out more, but it's also been slow to feather and is smaller so maybe it's just developmentally behind and the neck looks thinner/longer because it's not totally feathered? Anyway, none of them are developing combs at all. What do I look for and when?
THANKS from this excited newbie!
