Designing coop for 3 chickens. I am interested in using the Deep Litter Method for two reasons, less maintenance, and two using the litter for garden. My question is I have seen two methods, one the bedding is layed on a wood floor in the bottom of the coop and the other suggests just layering it on the ground becuase it says it will help with the composting process. I would like to use just the ground with not floor. Pros/Cons? Comments, suggestions? Will I have weeds growing up into the coop?
