Have you gotten any of your birds to fly up on the perch on que? That will be the challenge. I can get them to go 8 feet up but training time more than most keepers of games likely to invest. Getting them to go higher is likely more a measure of the keeper than the bird itself as most in good feather should be able to go 20' vertical when properly motivated. It is the motivation part that is the problem. Birds kept on tie-cords and pens in yard will also have some conditioning issues.Not done yet... but one step closer to adjustable high fly perch. Right now, it can adjust from 7' up to 13' (might reduce depending on how roosters do in tests). Quick assemble and disassemble. I am going to add wood to the perch Also want to add tie cord to the perch. and maybe some rigging cables or gussets to stiffen the whole thing.
