Looking sheepish

Amazingly this is my first sheep blip.
A few months ago I photographed the early morning frost in this field. and was surprised to see that it had been planted with what I thought were Brussels Sprouts (it has always been just grass/shrubland). Now the sheep have been introduced for the first time and I hope, for the sake of the local residents, that they are not munching their way through a field of Sprouts.
