trench a line with a shovel. some ground protecting wire has to be 2' in most areas, but if ran inside pvc conduit it can be only 6" deep. that's easy to dig and lay. I connected power to my shed off an outdoor outlet. We already had a breaker for the patio, so now the shed and patio are on the breaker together. It's not much power pull unless I'm running power tools, but haven't come close to popping the breaker yet. just a 120 amp is fine. It's relatively simple electrical work.I don't have a way to run electricity out there without the puppies eating an extension cord and I couldn't stand the smell when they were inside. Fortunately we don't have heavy predation here. Mostly owls and hawks and the quail are in an aviary.
Are your quail the wild tupe or do you have different colors?
