I have tried to read up on this, but found some older threads on it, and decided to ask anew. We have this one young hen, who has decided she will stay inside the fence with the others..... So, they have about 1/2 an acre fenced in, plus an entire field behind that, about another three acres, and everyone else is happy to stay in their own big roaming range, except this one pesky hen. She gets out numerous times a day in our yard. Her main goal is to get into the shed where the hay is stored (local grass hay we use for their nesting boxes). If it is open, it is a sure magnet, so I make sure it is kept closed. Even so, she gets over the fence, stand there and calls and calls desperately hoping she can get in. She is tough to catch too. Once caught this last time, I clipped her wings....that DID NOT do anything. She keeps getting out. Now I plan to have the guys add height to the fence, but in the meantime I grabbed her, brought her back into the chicken yard, into the henhouse, putting her into the nesting box, within seconds she was out and pacing the fence again. I speculated it may be she just got out that one time, laid her first egg (she and 7 others are just starting up) in that spot and has decided that is where she must go now. Is this her issue? Do they fixate on certain spots once they lay an egg there? What would help, other than fencing, to break this habit for her? If there are a lot of hens in the flock (mixed ages, some older, some young and some pullets yet), will they feel "cramped" for space if they perceive there are not enough nesting boxes and try to expand their laying territory? Another thought, would adding another devoted nesting "room" on the exterior of the henhouse possibly help? My son did put the nesting boxes, I thought, too high. All the hens are used to it, and he thought it would make them feel safer when laying. Should the boxes be lower in the henhouse?
