I have a flock of chickens that graze the upper slopes of my property between swales. Their manure migrates into the swales, feeding the trees on the downslope berm. They are moved weekly along this two acre stretch of property. The chickens benefit from fresh ground, insects, and vegetation. They are healthier and consume less feed in the process. The only negative is the work involved in setting up and taking down the electronet fencing each week.
