Definitely a girls' club.
From Storey's Guide to Raising Chickens:
"Two temporary methods--brailing and clipping--are used to control young birds that will eventually grow too heavy to fly. Brailing involves wrapping one wing with a soft cord so the wing can't be opened for flight. Clipping, the most common method of controlling the flight of backyard chickens, involves using sharp shears to cut off the first ten flight feathers of one wing. Clipping causes a bird to lack the balance needed for flight...Two permanent flight-control methods, pinioning and tenectomy, are more often used for game birds than for chickens...Pinioning, like clipping, controls flight by creating a lack of balance between a bird's two wings. it is a surgical procedure requiring sharp shears to remove the tip of one wing at the last joint...Tenectomy calls for removal of a section of one wing's tendon..."
Walkabout is not a small hen. Heck, I thought she was already too heavy to fly. Lightweight netting secured over the run is also suggested.
But here's the deal. Walkabout marches to her own drummer. She doesn't care if she's with the flock or not. She's the only hen in the bunch that feels this way. The others go everywhere in pairs or in hordes. What one does, the others do. Except Walkabout. A rugged individualist with the brains to get herself out of the cage and free. In my heart, I identify with her. So as long as the weather holds the fox and other predators at bay, I can't do it. While I see the danger that she doesn't and while I have the responsibility for her, I also feel for her desire to go her own way. I can't blame her for 'going over the wall.' Crazy chicken. Crazy owner.
That's not Walkabout in the userpic. She was on the OTHER side of the fence.
