I want to start a compost in the spring. We have PLENTY of space, but I want it to be an adequate size that I can still turn it by hand (no machinery). First of all, what all can I put in it as far as animal waste... I have heard that dog waste is not a good thing to mix (too bad, we have a dog boarding facility), but I have chickens and rabbits. Also, what CANNOT be composted. What time period am I seeing until I can use the compost?
