Ok. Both rounds are up and flying. The older ones are picked out and released to not bring the youngsters too high where they may be lost. As they reach a good height, usually about 15 minutes in, I release the younger ones. They kit immediately within their group, but trap together with the older birds when they come down. In less than a day or so they will be kitting and trapping together. It's not a perfect formula, but it is quick and effective. Easy as could be. Enjoy.
