I can't add much to what it's like to live in Ireland as I've never been there. However, I just wanted to add to research what animals you want to keep, and be sure how you are either going to get your stock there, or, be prepared to buy stock over there.
We exported to Ireland a few times, north and south, and it isn't easy. Regulations are different to here, and if there is any disease risk over here, ie blue tongue, FMD, then they simply won't let in any animals from the UK.
Ferry costs for trailers are expensive I do know.....
But in terms of life quality, I think it could be a good move. Will be interesting to see what people who have done it already say.
