Not a fan of caponizing here. While I totally respect the decisions of others on how to keep their birds, I am not partial to painful procedures that occur without pain relief - - in any species. So, what do we do if one [several] of our beloved chicks turns out to be a [several] rooster? - - Have a friendly, frank talk with the neighbors. Bringing eggs doesn't hurt. Seriously, you won't need to worry about separating anyone until/unless some aggression surfaces. If there is plenty of room and the birds have grown up together, you may be able to reach chicken adulthood without too many problems. In any flock, there must be 1) enough room for less-aggressive birds to escape; and 2) enough feed/water stations for less aggressive/active birds to feed in peace. This goes for roos OR hens. Good luck with your birds!
