Three of our chickens... keep escaping!My neighbor and I clipped their wings but they still fly over a 4 foot fence!...
Clipping a chickens wing is not intended to keep them inside a 48 inch tall fence. Anyway most non-fluffy butted chickens with clipped wings can still clear a 4 foot tall fence. And even if they can't top that fence chickens are very good climbers who can scale the Empire State Building if some forgetful person leaves a step ladder leaning up against it.
