I've read many threads on here about controlling flight of chickens. We have five Araucanas (probably not pure strain) and six mixed hybrid pullets hatched in late March, early April. Only one is laying so far, that we know of. Our problem? They are flyers. The first seems to have taught the others. Our older hens stay put in the chicken yard, wait for free range in late afternoon, but the young ones escape at will. I've already clipped one wing on each...this does not contain them. Their chicken yard fence that has worked up to now with these pullets is a four foot chain link and we have no choice in replacing it or covering it (20 x 20 yard area). My question, should I clip both wings? Will this hobble them to the area where I can keep them safe from our dog? I understand the purpose in clipping one wing only--putting them off balance. What will be the effect of clipping both wings? Advice please, or other suggestions. Thanks, ~G
