I posted on the other thread as I didn't know about this one yet. Buy a 16' sheep panel and bend it in a circle inside the fenced goat area. Connect one end to the other with carabiner clips. Put the buckling inside with water and hay, you can feed him inside as well. You can just drag it around the back yard with him inside it for fresh grass/soil. I say a sheep panel because a cattle panel has 6" holes and baby goats can go right through them. You could do the same thing with a left over section of regular fencing, but would need support for it like T posts. Place a crate inside for him to sleep in.
