I have a 46 inch fence around my run with no top. Because it's open on top, I've been clipping my hens' wings - both of them. However I've been reading that many other people clip only one wing to prevent the hen from having the balance for flight. Is this more effective? Would this lack of balance created when only one wing is clipped make it hard for them to get up to and down from their roost overnight, or make it difficult for them to get up to their raised nestboxes, which are about 16-22 inches off the coop floor? I'd love some feedback on which wing clipping method is preferred by BYCers and why.
