Also depends on the field - hay will make in 3 days on our most westerly field, where it gets both sun and wind, but needs 5 on the easterly one which is sheltered and has a shady area along one side. We plan to go into Winter with more grazing than last year, since the grass was so late getting going this year, and are buying in some of our neighbour's hay. Hopefully not from his damp field where it's full of buttercups or the one with lots of knapweed, which shatters in the hayrack and more of it ends up on the floor than in the sheep .....
