Wow. Those are all roos. I have Buff Orps and none of them at 4 1/2 months even have combs and waddles like yours at 5 1/2 weeks. Mine don't have any at all really. Sorry
Yeah, I called the hatchery and told them of the error. One of the owners is supposed to call back. I drove 2 HOURS to that hatchery to pick those babies up and 2 HOURS back home!! I waited 1-1/2 months for the order to be filled.
So far, no call back.
I will call every day until I get a response.
I am soooo disappointed. NOW, I have to re-home all of them and it is very difficult. I'm afraid they will start getting rough with my bantam hen, if you know what I mean....
My buff orp pullet is just over 16 weeks old and she still had no red in her comb and her legs are much finer looking than your chicks. I think they are all roos.
