We built our mobile free range egg trailer last winter and got a bunch of chicks, brooded them in it, then started rotating them around our farm in the trailer. They get along pretty well and we have some extra space in the trailer, especially with the losses we've seen from hawks in the last couple of weeks and there's space in the trailer for more birds (we have somewhere in the high 30s as far as numbers go). I wholesale eggs to a woman who has a small flock of chickens who are also free ranged in a mobile coop. She has too much going on with other farm endeavors and is wanting to sell her flock to me and just buy eggs from us. If I end up doing that, I'll split her flock of ~30 birds and take half of them, the other half going to another friend who also wants more chickens. When adding ~15 adult chickens to an existing flock, with no simple way to keep them contained, what's the best way to accomplish this?
My thoughts are to get a used stationary coop and set it up adjacent to our garden area where the chickens will be spending a large portion of their winter, and make that the new flock's home, then slowly move our mobile coop closer to that area until the birds have had a chance to meet each other and sort out pecking order, at which time it should be relatively simple to transfer the new flock into the mobile coop at night once everyone's asleep. Is there a simpler way I can execute this? Since I don't have any containment, I'm hesitant to just toss everyone in together without first establishing our farm as home base in case the new birds decide they don't like what I'm offering plus the aggression from the established flock.
