My RIR hatched 8 adorable chicks. But I have to be very careful to keep them separated from the other 3 hens and rooster, because the other day one of the hens grabbed one of the chicks and flung it. It probably would have killed the chick if my husband hadn't intervened. (The husband who doesn't want anything to do with the chickens - ha ha) It seems like nature would end up with zero chickens if every hen's instinct was to kill chicks that weren't hers. What's up with that?
