Not sure if it has a bearing on things or not, but all my birds were trained to the fence from an early age. About 10 weeks of age. And all trained by a single, low strand. Wire or tape. All of them would step on it to go over and got zapped on the bottom of a foot doing it. Once that happens......they seem to fear what is on the other side. I've left it off and it took a week before any of them crossed it. But once one did, they all started. Turn it back on and all that stops and they stay in again.
Then once the birds are trained to the fence.........I start adding wires to get to a height that dogs and other predators can't simply step over. Two strands might work if you bait it to start. I like 4.......and I bait those too.
For a lot of reasons, I've had better luck with fences than poultry netting. Birds may fly over poultry netting.......they see it as a physical fence. And it is harder to maintain. But probably better protection from foxes, coons, etc. Netting fences are expensive, but not much is going to get past a well maintained and properly setup netting fence.
