Love my chickens and especially the eggs. If you free range them they will dig up all of your permaculture. Took me awhile to get my dogs used to the chickens so they wouldn't mess with them anymore.
About your Coop, if it doesn't have a wire mesh bottom you need to bury chicken wire or wire mesh for about a foot and a half all the way around your perimeter to keep predators from digging under the cage and stealing your chickens. I lost one that way to a fox.
