Wing bands are great for adults, but cannot be used on newborns. My Cornish have super sized wing muscles so I am not sure the wing bands will fit well. The metal leg bands the Vet had for my NPIP certification did not fit around my Cock bird's legs either. So for me I'll stick with my track-able from birth to adult system.But you still have to replace them every so often. I think I'll stick with my $.08 wing bands.
