I have several questions for those with experience with Premier's electric fence netting. They have a number of options, and I don't want to spend money on things that don't improve its usefulness. I've decided to go with the white PoultryNet Plus (so that's two decisions out of the way). Other options I'm hoping people can weigh in on: 1. 42" vs. 48"? I think my chickens could fly over either. (And my main concern right now is confining them. I posted in predators and pests, because this looked like the best place to put this question.) I'm assuming I'll have to clip their wings with either height. Is there an advantage one way or the other? 2. Single spike vs. double spike? The double spike looks like it might be more stable, but I also have very rocky soil. The thought of having to drive twice as many spikes into the ground - each time risking an encounter with a rock - isn't appealing. I'll do it if there's a benefit. 3. Length/Kits. The kits all come with 164' fencing. That's way too long for my needs. That would nearly enclose my entire property. Should I skip the kit thing and buy a shorter length? If the fencing you have is too long for the area, can it be folded or rolled in some way to shorten it? I'm working with a very challenging space. It includes many trees, a slope, and no one area with a large square or rectangle could be made. 50' seems too short for an adequate area. (I have six hens.) But 100' may be too long. Thanks for any advice.
