We are starting our flock in the spring with 12 layers and 6 guinea hens. We also want to raise possibly two batches of meat birds before the winter. Our winter-proof chicken tractor cannot hold all the hens and 12 meaties as well, so I plan to build a more temporary chicken tractor for them, but also let them free range still. Is this going to be super complicated to have both flocks free ranging and then get them into their separate pens at night? Should I shoot for one big coop to hold all of them instead?
