We already have a derrogation not to use tags before six months for ouessants and I notice some of the old photos have pastern bands on them. My solution would be to only band them if they were leaving the property for some reason but to use management tags from a young age so the two would work quite well. From what I understand the issue here is not for finding a manufacturer but in getting approval although I think this will come as bands are on the aproved list.
