But be careful about letting them into your garden. They'll eat EVERYTHING, and what they do leave could be ruined by their droppings because of the ammonia content. Same goes with composting chicken poo, you have to let it sit for quite a while to get all the ammonia to neutralize, otherwize it can act like acid and kill your plants. Now that my garden is done I'm going to put all my droppings on it over the winter and just let it compost naturally without having to do all the turning and adding and what not.
