I live in Pomona and This is my run, I have 7 Barred Rocks, 2 New Hampshire Reds, 2 Ameraucanas, 1 Cayuga Duck, & 1 Pekin Duck, 1 Labrador Retriever, 1 Siberian Husky, and 3 kids lol . I converted half my shed into a coop and I let them out into a secured yard daily. The dogs are not trusted around my flock
