Hi All, not sure that this is the best forum to ask this? My teen daughter is interested in breeding olive Eggers for fun. We have 13 pullets and four cockerels. Currently two cockerels (6 and 8 months old) are in the main coop with 11 pullets (6-8 mo) and six ducks. Older cockerel is boss. Have a silkie cockerel in a tractor and copper marans in a grow out pen with two pullets. We are working on a new 3x7 ft coop with planned 7x16 ft run. Intended to put all four cockerels in that new coop/run, remove one as needed for a few hours or day to breed, then return. However, yesterday we let all birds outside together and all cockerels fought. My question: is this an unworkable plan because the roosters are now too old to be introduced together and will kill each other? Considering whether to split the new coop and run and try housing as two pairs of cockerels? Thanks!
