Most new fanciers do not have an elaborate setup, nor do they have a lot of breeders to start off with. This means having to mix smaller hatch rounds to form one single kit. It's not difficult. Keep both rounds together, but train them seperately. In this video, there are 15 in round one, and 9 in round 2. I work with the younger birds while the second round are flying. I used a cage to illustrate how easily they will trap with the younger birds. When it is time to fly the younger 9 birds with the other 15, they will kit immediately, they know the older birds very well, and the older birds will accept them with no problems. At that point you can train them as a group. Enjoy.
