I just moved my 5 girls from a coop/run into a 4x8 chicken ark. My plan is to move the ark once per day onto fresh grass, and my lawn is big enough to give each section of grass about 10-12 days of "rest" before moving the ark back onto the same spot. Do you think that will give the grass enough time to recover? I know how quickly chickens can decimate grass, but I also want them to have the health benefits of being raised on pasture. Anyone have any experience with chicken ark rotation in their backyard?
