So they had a day out. When Peter and Fred arrived on Saturday morning, half of them were in the polytunnel eating hay and the others were down by the cabin eating rosehips from the shrub roses.
So, Peter and Fred decided to move the gates so they have free access into the hay supply in the polytunnel. There is nothing else in there anymore since we harvested all the pumpkins and squash. They will be able to sit in there when it rains if they want a change from their shed. I'd rather keep them off the roses though (and the rockery which has taken me years to nurture!)
