CB100, with your post being on a Sunday afternoon it may take a bit longer for responses... I don't deal with show birds, so not too sure, but I have used simple bird netting over my run to reduce overhead exposure (but my run is 8ft tall chain link, so taller than most birds would fly anyway)
The bird netting is found at any garden type store or often at feed mills and such places, it is used to protect crop berries and trees from birds. They also have 'deer netting' I believe, but I am not familiar with it.
