Nice tactful response from Landroverroy. Really tough to give up keeping livestock due to old age/ infirmity. It is a decision we all have to make eventually and sadly some otherwise very diligent people leave it too late and let standards slip. Quite possibly the row was about just that. As a concerned individual you have a role, and as a landowner you have a role, other people will make the assumption they are your sheep after all. The only thing I would add to Landroverroy's comment is to mention fly strike was an issue last year- it is looking like a damp and warm summer and can he arrange for them to be checked daily as you won't be around every day/ as much as last year?
