How well will two adult roosters, previously in a flock with hens, do if kept without hens, and penned/cooped together? My brother has two large roos who brutalize their hens (granted, there aren't enough hens for two roos), and it is at the point where separation seems the best route. (My brother will not do away with the roos, in any manner). He wants to build a separate coop with a separate run, and keep both roos together in it, where they can hear but not see the hens. Both roos lived together previously, but did so in a flock with their hens. Is he setting up a cock-fighting situation with two hen-deprived roos, or can this bachelor pad work for him? Or, is getting more hens the better solution? Thanks for your input, all!
