We have a premade coop with a fence around it giving 4 chickens about 10 ft by 10 ft total to run around during the day and 6 by 4 during the night once they are cooped up. The inside of the coop part (was grass) is now dirt and poop. I was thinking I could shovel and put on the compost pile? Ideas? Will that work? How often do I scoop it up?
