I clip when they need it and as young as possible so they get used to it being done - if I have time more often instead of waiting till they need done and can't manage for some reason so what I mean is about 8 weeks / 12 weeks (but a little trim) then every 8 weeks unless I notice someone needs done - I have more of an on demand program than timetables - hope I've not completely confused the issue - and again do dairy grow quicker or slower than pygmy - not sure on that score - maybe I should stop posting and leave to more knowledgable keepers!!
