I had looked at Sandhill's website, and narrowed down to these breeds that fits the looks of your chicks-
Red Chantecler
Rose Comb Rhode Island Red
Red Pyle Cubalaya
As for the smaller chicks, if they are bantams- The only breed that fits are- Ameraucana: Multicolored, pea combed. Some are non-bearded, as I do not see any single combs on them.
Thanks Farmerboy. Unfortunately, the reddish chicks are feathering in white, don't know if any red birds have white feathers when young. I am sure that the little ones are not Ams.
