We have an escape artist of a chicken. In the past after her molt she would discover her wings were no longer clip and resume her daily flight over our 7 foot or so fence to roam the feral-cat filled neighborhood She recently finished molting and once again discovered she could fly over the fence again. No problem, we'll just clip a wing. Then, a couple days later, she's out again. There don't appear to be any holes she could crawl under, nor things she could leap on to reach the fence. She got out before I had to go to school and I've just received word she's missing again. What can I do to stop this?
