My Orps are, or course, much larger than my young bantams, so I have given the bantams very little time out in the backyard. However, as long as they have room to roam, the orps don't bother the bantams so far. Trouble is, they need to share the coop soon. The bantams are quickly outgrowing their brooder, and are feathering up nicely. I've read that orps are calm and will accept smaller birds. How can I go about introducing them to one another without harassment from the larger hens?
