According to the Purely Poultry blog ," Production Reds are a
true breed derived from Rhode Island Reds and the New Hampshire. The
Red Sex Link is a
hybrid, created by crossing a Rhode Island Red male and a
Delaware Female. The
Cinnamon Queen and the
Golden Comet are
hybrids also. They are excellent layers and even mature a bit earlier than your typical chicken. " Your chicks could be any of those.
There are slight coloration differences between all these types when they feather out into adult plumage which will hopefully help you pinpoint exactly which ones yours are. I think all the chicks are almost identical though. I believe the Production Reds will pass their traits on to their offspring but the superior egg laying traits of any of the hybrids listed above will be lost with any new generation coming out of the original hybrid stock. Maybe someone can clarify this a bit better for you.
