I just ordered some wing bands and have a question about putting them on. What age can they be put on the bird? I heard any age is fine, from day old up to full grown birds. I ordered the Jiffy Wing Bands that use the 893s band sealer. Do you first push the band through the wing webbing, then line up the sealer and close the band, or put the band right in the band sealer and pop it through and seal it?
