A Dexter bull! My fiance's dad has one, and I took my Jersey there to have her bred. So, now I have a lovely half-Dexter heifer calf! I don't have any experience with Dexter cows, but the bull was a good one. Nice (for a bull), short and stocky, easy keeper (on grass and hay alone, he was actually becoming a butterball). His calf a little firecracker: super healthy, active, well built, and already a good grazer at 6 weeks.
Hope others can give you more info. I think they are a great breed!
