I am very much in the US. I have games. Tons of predators. Fox coyotes hawks bobcats possums coons skunks owls eagles mink and bears. Had turkeys, guineas, and different kinds of chickens through the years. Game chickens have been the only thing that increased to above stocking levels. They have plenty of cover here, they will use that to their advantage. I do provide some predator control, but basically they hang around where there is larger livestock and they spend a lot of time around my kennels where I keep a few hounds. Favorite roosting spot. Turkeys and guineas wandered too far into the open. I still lose a few chickens. Natural culling, the dumb slow ones have no place passing on their genes. The good proven ones get some layer eggs put under them if I know where their nest is. The very best go in a breeding pen. I want chickens to eat waste grain and spread poop and eat bugs and ticks. Sometimes I have to cull aggressively when the hordes of woods grown game chickens start to become a nuisance around the barn getting into things. Possums, coons and skunks will be removed if they get to familiar with the place. If a fox, coyote or bobcat gets one I am overjoyed, because that bird was not alert enough for my program or didn't know how to pick a good place to roost or nest. Those predators need their energy to provide hours of entertainment to the hounds. Don't have much problem out of hawks, keep a rooster loose that could probably take them, and the hens and young usually listen for him to tell them when it is time to hide. Yard roosters are seldom straight American Game, they usually have some oriental influence so instead of a four and a half pound bird he is more like seven. I pick one that is not too hot, keeps the stags in line, but doesn't go out of his way to kill them before I have a chance to pick through them and look at toe punch marks and put them in the eat, sell, or keep and watch develop pens. I hear owls all the time, I guess they don't like the dense branches over the dog pens where chickens prefer to roost. I don't think any nest real close, because I leave crows alone around here and have a huge flock that share the carcass pile with the chickens. The owls and hawks don't really have a good vantage point to get the feel of the place, because all the big trees with dead limbs have had a date with Mr. Chainsaw.
