Hello all! We just recently moved to the Nevada dessert and it is finally cooling off to where I think I am gonna try a garden. I am in the process of building 4x8 raised beds. I am only building two due to the fact we live in the dessert. My plan is to build heavy duty tractor type of cages that can be placed over the beds (I got the idea from GardengirlTV.) Now to my question what kind of animal should I get to fertilize the beds? I am building one tractor to go over one bed at a time. My plan is to have them in one bed for a couple weeks then move them over to the next bed. I am going to place a tarp over the bed im not using so it can compost. I was thinking of either getting a couple of chickens or a couple of rabbits. Which is best? I will have to build these heavy duty and predator proof as we have a coyote that lives in a bush next our house. I see him all the time. Thanks any advice is much apperciated!
