We have several roosters, but two in particular are just inseparable. Our two Faverolles roosters are never very far from one another... it's very strange. They never fight, although occasionally one "dances for the other for a second or two. That's always ignored in a dignified, world-weary sort of way. Almost as if they were British birds, rather than French: "Really, old chap--that old game again? I say, it's MOST boorish of you."
Then they continue taking their turn about the yard. I bet they'd like it if I could fashion little meerschaum pipes for them somehow.
My other roosters don't fight, either, but they will face down with their hackles out like ruffs, and the one who loses the game of, um,
chicken, then runs away. I have a lot of room, though. I think the more roosters you have, the more room you have to have.
With my two Faverolles, though, I don't think it would matter if they were cooped up or not. They're real pukka sahibs. I've had other Faverolles roosters that didn't bond like this, though.
