What I have been doing it setting up a table a few feet away from brooder. Then I reward chicks for coming to me when called by giving them a meal worm. As training progresses they are expected to go farther or do more to get the reward. You are likely to see they want a bigger reward to go farther. I try to get them to go from brooder to that table. At first the birds may walk along a ruler or make a series of hops. Then I push for more direct flights. Mine eventually get to point where they fly 20 feet across the room.I can try, they are in a plastic bin as their brooder because I want to keep them inside.
Is there a way I can make it outside the brooder?
