I've always liked the idea of keeping backyard chickens for eggs, and this recent salmonella outbreak has really spurred me to start researching what it takes to raise a few birds in town. One question I have, that I haven't found addressed in any of the books or threads, is "do I need to do anything to disinfect the ground before building a coop?" I have a dog, and the neighbors have cats. I have seen and trapped raccoons, and there are squirrels everywhere. I don't put poisons on my lawn, so I suspect that there may be some parasites and bacteria in the ground out back. Is this a concern in starting a small flock, or should I just not worry about it? I'm really not a germophobe. I just don't want to start off by making my chickens sick. Advice?
