I am trying to decide what/where to put our coop. I am not sure how mobile to make it, first off. I guess it is best to be able to move it once a week/daily for the grass and to fertilize. But I am not sure how feasible that really is. I am not a craftsman. So more then likely, our coop is going to be permenant unless I have a WOW moment. I know there are kits to buy, but they are so expensive. Anyway my question is what is the best outside flooring for the coop? Just let the grass go to dirt, put dirt down, put down gravel (if so what kind), mulch, .... Thanks for the suggestions on my first place to start! oh and if it helps, we are thinking 8-10 hens.
