Of course I think the Jersey cannot be bettered (
), but I am not sure I would want Hillie to outwinter with only a field shelter up here. They're fine doing that in Somerset!
I've been trying to get a cross of Red Devon / Jersey. No luck this year but I'll have another go next.
Some people rave about Dexters and others say they can be rather hot to handle. They should be hardy enough, though.
What about the local hardy breeds, the Galloway, the Whitebred Shorthorn or the delightful cross of the two, the Blue Grey. We have several Blue Grey suckler cows and they are just lovely. Very very hardy, very very quiet. They are best not put in calf too early though; they don't really want to be having their first calf before their third birthday.
I'll be interested to hear what you get and how you get on with it!
