Circumstance has led me to owning a single full grown Bob hen. I have an existing covey of 18 Cots in a 6X6 pen. Can they mingle?? Will they fight? The cage is quite large and has hidey places. But if its not meant to be, so be it. I can rehome her if she will get lonely living solo. I didn't like her old living situation so I got her. Haven't thought much further than that. Lol My new "Pidgey"
