Newbie here needing advice. I have 2 breeding pairs of bantams, Old English and Buff Sebright, that I would like to make a duplex coop on slides or a tractor for. I saw the duplex in the coop section and liked it, but I would like to see other ideas too. Or would it be better to have 2 different tractors, since the roos might be challenging each other against the wire? These are my first chickens.
