I am thinking of getting a few sheep but as I live on a water plant the 2 acres of grazing land are all long strips of land with water beds either side. There is no way I can fence the grass from the water plants as we would not be able to run our nursery. Are water plants poisonous to sheep? Also the ponds have a mixture of concrete sides and soil banks so there is a few inches drop to the water but obviously more to the bottom of the ponds. Are sheep determined to hurt themselves or are they likely to steer clear as I believe they don't like going in water?
