I don’t think they are doms…they all have single combs. None of those have wattles yet. But tomorrow they will all be 3 weeks. I’m sure not all about pure breed. It would be nice to have some that are but I’m gonna love them just the same.They look like BRs. They're hatchery quality, so may have some physical traits that don't conform to APA standards. But, they're females, will lay eggs and you'll learn what breeds fit your needs best. You may get an accidental male oops, but so far I don't see any obvious cockerels.
If any of those have a flattened comb, then it's probably a Dominique. BRs are more popular, but those Doms are very nice.
I’m excepting at least 3 males. But I don’t really see the hatchery giving me males intentionally. Only because then they would have to refund me. Really only time will tell. And they are all pretty playful, flying at each other and what have you. So there really isn’t anything standing out to me…at least not yet.
