Have four 'coops' at the moment - one is a growout coop that was pressed into service for adult birds. ALL of these birds free range together and hang out together and go back to their respective coops at night. One roo in each of the two larger coops, although when let out the two roos pull a switcheroo and run to the other group of hens. Fickle beasts! I need to get the number of coops down for winter. Will sell off some birds, but anyone expect any trouble if I merge two groups of free rangers in one coop? I plan on doing it when I'm no longer letting them out (snow on the ground, most likely) so they'll be stuck in the coop/run together. Or should I do it earlier? Just start putting the smaller group (5 hens) in with the larger each night? Not sure if they've worked out a pecking order, but they do all eat together during the day. Second question - anyone foresee a problem switching roosters? My 'back coop' rooster immediately runs up to 'his' girls in a different coop and the roo from that coop has recently discovered the abandoned 'back coop' girls. Might as well switch roos for nighttime I would guess, right?
