i use whistles to tell my birds what i want them to do, after training them in the loft to do so, whether they listen or not, has admittedly been a problem lately, so i got a long bamboo pole to whistle then tap were i want them to go when training, then to chase around till they stop ignoring or evading me while making another sound, then original whistle and tap again and they fall in line with rest that then are just watching those get chased, while they calmly perch or snack or preen. soon just the one sound or certain sounds get them to do as you want. this and enforcement with a frisbee or boomerang free flying has stopped most of issue now as long as i keep up the exercise every so often. otherwise theyve just been hanging out and preening up somewhere or walk around hunting for rare stray snacks, and try to nest. im keeping my sexes seperate when in, and out, but not stopping problem, even hens on grates are laying still, and trying to make feather nests, actually incubating to point if left with eggs that eggs start developing before i toss them to the dog. when sexes were let out to fly together and visit, they would mate. pigeon pellets are not seeming to provide enough calcium, that layer pellets, conditioner pellets, and types and mixes of with calcium grit did (but the directions on pigeon pellets say no need to feed grit and it can be bad to feed with it).
