I have started doing sheep and goats recently. Their primary purpose is to help manage landscape in part for chickens. Strip grazing is being used when forage has not been under snow. When snow covers ground, they stay in place longer as hay allotment becomes more important for meeting needs. During periods where they are not moved as much, they really chew down the vegetation, even trees. Some of tree consumption is out of boredom when they are getting lots of hay. When moved as desired there is lots of vegetation remaining although they still do a little feeding off the trees. Soon I will be seeding with legumes and a cool season grass that will be used to stockpile forage for next winter. Later as herd grows and spreads most of ground will be managed for production season pasture that will also be subjected to strip grazing. Hope is to have chickens access much of those areas after they are grazed during recovery phase for plants.
