I recently bought 5 adult buff guineas. These silly birds will hang out in the barn for a good part of the day, but when all my chickens come in to roost, the guineas go outside and fly on top, or in the trees or anywhere else but in the barn. Any ideas to get them to stay in? It doesn't have a door, unfortunately, that would be too easy! Or will they be okay to stay in the trees? <Edit> One of my guineas, I think it is a rooster, is roosting in the building with the chickens tonight!!! Hopefully the others will follow his lead, so I don't lose any!!
