These are all barnyard mutts- they're mixed between RiR, barred rocks, new hamphire reds, and easter eggers. Many of them have the puffy cheeks of easter eggers.
They were hatched the 1st and 2nd of October, so they're about 5 months old or 20 weeks. I know the big black barred rock rooster is a roo, he crows (and has since he was teeny tiny). He is about a week older than the others.
We are in KS, it has been warm, and we almost get 12 hours of sun I think. They aren't laying, and many of their combs (the ones I am mostly sure are hens) are not red and filled out.
1) in the pics, which ones are def roos, if you are able to tell?
2) I had RiR girls before in AR, from a May hatching and they were laying at the end of August/1st of Sept that year. So I am anxious if these girls will start laying soon?
