Also just leant that the German's apparently have to send the droppings  to a Vet etc. in a Goverment ruling ... most I should think just send the Best selection and substitute any poorer ones at the time with these also.

So thought and idea in theory is good... in reality another complete waste of time as far as I'm concerned. JMO could be wrong :-/
