Hi! We have 3 flocks of chickens one consists of 6 hens (no roos) another slightly younger "flock" of a rooster and a golden sex link, and the last was a group of significantly younger Cochin bantams and a silkie. Two of those are roosters an the other was a hen, who has now passed. Now the two rooster fight even though there still young. One of my friends is interested in the silkie rooster, but I can't leave the other alone. So here's my question: would I be able to introduce the Cochin frizzle roo to my significantly older flock of only hens once he's a little bit older?
