i want to let the girls out some to free range in my yard, but i dont trust them at all. they scatter when i walk into the run and they wont come near me. so how am i to trust them outside the enclosure? we got them 4 weeks ago when they were 16wks old, and they were not handled at all by the previous owner. they spent all day free ranging and roosted in the trees. what should i do to be able to let them in my yard?
