I have this idea to use my new Jersey Giants (that I'm going to be hatching ) as weed whackers. They are so big, and I figure I'd let them free range most of the time. But I want to concentrate them in one area so they will keep the fence line grasses down. So I need something like a chicken tractor, but not that confining. Something easily moved and reconstructed. Like snow fence almost. It's not really to protect them as much as to keep them in one particular area of the yard. I'm worried about the Roo attacking my sissy great dane, thought.
