Feb 22, 2018 · The leaf pile on the right in the Composting Chicken Coop is one month old. In the compost box, I can usually get usable compost in about a month. To help speed up the process, and to let the chickens have some fun, I will move the pile to one side of the compost box, wet it down, throw some food in there, and let the chickens tear it down.
