I have 10 weeks old layer chicks that are kept free range in a one acre yard with a five foot fence. So far I am not sure if it is because they were never interested in exploring as of yet, or if they are just happy where they are and feel safe, but they have not given thoughts of flying over it. I am sure if they wanted to they could fly over as they fly up on some wood perches near the ceiling of the coop. People have told me that I will have to clip their wings or they will escape. Is it true? If they are happy and have lots to explore, can't they just stay within the fenced areas? In Italy, people just kept their chicken without fences and they always used to stick around..
