See any roos? 4-5 weeks. EE type. I thought I had one. Then two now I’m not sure. They’re so loud the second pic I always thought could be a roo. Now the third one with the comb.
The one with the comb I'd say is a cockerel. It might be a little early to tell though, most suggest wait till 6 weeks old. (I know, I know, it's soo hard to wait! Got some straight run the other day and I'm going back and forth. )
