I understand about the rain and the dirt. I only meant for a slope the width of a path, for them to move up the terraces. Planks would do, but it seems easier to me just to knock the corners off each terrace. Well, you know your place, I expect one would work at well as the other.Thanks for the comments!
So if chicken wire won't keep the foxes out do i need a fencing with larger holes and heavier gauge wire?
Good point on the house size, think there is enough land space for more than two though?
Wouldn't want to flatten off the terraces as the soil here is very loamy and as terraces will help with water run-off it can only help with land slides which are a bit of a problem here, long wooden ramps would be ok though?
Do i need to bury the fence if i get electric too? And how high to keep out mr fox?
Can you get pig wire where you are? It´s like chicken wire, but really thick and larger holes, but the foxes shouldn´t be able to get through it. My dogs can´t. And then if you either dig the wire into the ground about a foot, or turn about a foot or 18" of wire out at the foot of the fence, then fix it down, that should guard against them digging underneath.
We use electric fencing here, and it´s really good as long as there are no power cuts.
We have a line running along at about 8" from the ground, and another that runs back near the top of the fence. Works very well. We use it to keep our own dogs out of the area that we keep the geese and ducks. One of my dogs is an absolute horror when it comes to getting into places I don´t want her to. Happily, she stays well clear of the places I´ve put electric fencing.
Just out of interest, one of my small dogs will chew through chicken wire to get them. It just isn´t strong enough.
So we use either pig wire, or chain-link fencing, which is a lot heavier and more expensive. I then run about a foot high 1" weldmesh along the bottom so little hatchlings don´t get out either.
Some of my fencing is 1.8m high where I need it. My dog doesn´t get past that, especially with an electric fence along it. I also have a fence with an electric line along the top that´s only about 4 ft high, and she doesn´t try that either, but I don´t know if a fox would or not.
Size-wise, depends on the amount of grass the area can provide for geese. If it gets covered in grass, you could keep a few there no problem.
