Here is a simple solution that will not cost much, takes little time, and let you enjoy your pets, rather than wish that you never got them.
Take three cattle panels (you can get them at feed stores, farm supply places, etc.). These are 16 foot long, 5 1/2 feet tall and have squares about 5 inches by 7 inches. Get three of these and cut one in half (they make a special tool to do this with...they're like giant wire cutters, however they cost about $30
) Take these now 4 pieces and make a rectangle. Wire them at the corners pretty well with any kind of wire (we use wire designed for electrical fencing...you can buy it in a 1/4 mile spool...needless to say, it lasts a LONG time!
If you don't want to buy some cattle panel cutters and can't borrow some (and don't have patience for a hacksaw), just use 4 cattle panels instead. It will be a little heavier, however.
Now you have either a rectangle or a square that you can put them in during the day, and move around pretty easily when they've finished eating!
You're happy, the goats are happy, and the neighbors are happy!!
