I have read in one or two posts about folks that have a "rooster pen." How do you keep several roos in a pen without them tearing at eachother? We are thinking about keeping several different strains of chickens - BC Marans, blue egg laying EEs, Cuckoo Marans a Welsummer or two, some barred plymoth rocks and some other general brown eggers - and want to keep some of the strains pure while at the same time making olive eggers, dark brown egging sex links and general brown laying sex links. My theory is either to have seperate rooms and runs in one house or have one pen for the roos, one for the hens and introduce the roo of choice for the cross wanted. Any thoughts? Keep up all the good work people!
