I have two new chickens that I am introducing to my flock of 5 Red Rhode Islands. My 5 that I have right now don't fly but these two young 9 month old do. I would like to eventually let them free range with my other 5 chickens but the previous owners said they kept flying into other neighbors yards. I don't want this to happen. Do you guys have any suggestions? Plus, how long do it take for the pecking order to be established and how does this work? Right now I only put my new chickens with my old chickens at night to roost and let my 5 older ones free range all day. Suggestions Please????
