I may have hit upon a way to get chicks to roost up sooner. Take a ground roosting group and move them somethere they do not want to be for a couple nights and remove original roost site. The release to they can go back to original area and the immediately start looking up at roost time. Brood shown here hen raised and already roosting over 6" up at only four weeks. Minimum vertical flight is 4.5 feet.
