Who is eating my blue flowers?

[VivienAnne]

I live in the country surrounded by fields. We have recently had sheep in the garden but they only seemed to eat the grass. However I think that we have had another visitor who overnight has eaten plants from the flower borders - all the blue flowers (primula etc) and helibor flowers. The heads have been bitten off and the flowers are missing. The daffodils were not touched. There are hoof prints in the beds which are about the size of a muntjac? However we are located in north derbyshire (High Peak) and I did not think that they would be around this far north. Any views on the culprit would be appreciated.

I know Muntjac are spreading north; if not this species possibly Roe Deer- they are also partial to garden flowers- roses a real delicacy!
