I have 3 hens: 1 Buff Orp, 1 Ameracauna, and one Silkie. They are all about 7 months old, hatched mid-April. We got another Silkie that was supposed to be a pullet but is definitely a roo. He was hatched 7/19 so is about 4 months old. I would like him to get along with the girls. Is it easier, harder, or the same to add a roo to hens as opposed to adding another female? He's pretty timid for a roo and runs frantically from our Seramas. (at least half his size.) Yet, he will dominate the cats!
