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?
You can introduce new roosters to the flock if done slowly. Just as mixing in any new hens, keep the new bird behind a fence or in a cage, but within the flock. Everybody sees, nobody touches. Even within hen flocks, there is a flock leader and hens can reject roosters. So let them all see each other like this for a few weeks. They can get to know one another in a safe manner and pecking orders are not upset too quick. This also gives the new bird some quarantine time if he is carrying any diseases. After several weeks, you can mix him in. Most of the aggression should be worked out and hopefully the hens can except the new roo. Of course you need to watchful for that first week to make sure he is accepted and always intervene if it turns bloody or he is not accepted into the flock. Good luck with your flock and enjoy BYC!
Hello and Welcome To BYC! TwoCrows gave you good advice above, BYC also has an article on the basics of integrating chickens https://www.backyardchickens.com/a/adding-to-your-flock ... usually adding a mature rooster to a flock of hens goes easier than adding another hen, even if the roo is smaller, so hopefully your guy will be fine with a little patience.
