The clipped wings have absolutely nothing to do with a birds ability to mate. I have just the opposite situation. I have a male normal grey that's caged with a 4 year old pearl hen. HE want's to mate with her so bad, it's driving him nuts! The problem is: she wants nothing to do with him......or any other male for that matter! We got her as a baby and she's now 4 years old and has just never shown an interest in breeding! As much as we (the owners) would like to pick and choose who mates with who, it doesn't work that way. Just like human's, the birds do the picking.
