Milk Kefir grains

I have some milk kefir grains that I have had for about a month now. I bought them online and have been using them with raw milk from biologically farmed cows. Every few weeks I have too many grains (as it grows). So when requested I may not have some to give straight away. I live in Dargaville, and can do post or pick ups. 

This is where I got them from - http://milk-kefir.co.nz/buy-milk-kefir/milk-kefir
