First the garden tractor. Sense I do not want the chickens eating all the veggies I was hoping to make a long rectangular frame out of PVC and cover with fencing. This is to fit between between the rows in the garden. I hope to put 2 chickens in at a time. My hope is that they will get the bugs and weeds but not the plants. I can build 2 or 3 of these to keep it rotating in the gardens thru the week. I know I will need to stake it down but should I cover a small part for shade? This will not be their main yard. Just a little place for a change for them and less weeding for me. The other question I have is the fencing we have is already installed. The coop will be built in the middle of their yard. The thing is I cannot bury any fencing. They are in an area that is so rooty that we cannot dig to bury wire. So the way I see it if it is to hard for me to dig with a shovel it will be hard for an animal to dig also. What do you guys think?
