I read about this some time ago and have only just got into doing it. Just takes a wee bit of organisation!
I bought 3x 10L buckets with lids which are the white sprouting buckets and already had an old yellow paint bucket (it's clean on the inside honest!). I also bought 4 small 5L buckets and drilled holes in the bottoms of these so that they can drain out the water but retain the grain.
Basically the system works by soaking grains (I'm using wheat but have tried corn, all sorts of other grains could be used too) for a day and night then put into a sprouting bucket and put the lid on. The 3 sprouting buckets are rotated according to the day and I reuse the sprout water 3 times before emptying it into the chooks drink water. They seem to love both the sprouted grains (which are apparently several times more nutrious than non-sprouted grains) and the water.
Now girls, where are the eggs?!
