Want to keep an animal species for poo collection for composting straw and leaves. Don't have any grass clippings unless I buy a new mower. I do have cow, mushroom, turkey, and chicken compost, as well as worm castings. But those things I have to buy and are used for a special soil less mix I use for raised beds. I would like to do it all from scratch with an animal that will provide the initial poo for composting. So far I'm looking at chickens or goats, maybe rabbits. Looking for some input here for ease of upkeep that will yield poo for a medium compost pile once or twice a year. And if I get a new mower, maybe more. We have crop farmers around here. Corn and soy and cotton mostly on large acreage. Believe they all do chemical spraying from planes. There is only one neighbor that keeps about a dozen chickens in their fenced back yard. I have not approached them about what they do with their poo.
