The birds love this food !!! For me, only pesticide-free organic food is in question, since the conventional production through the use of Pestziden's alone is counterproductive for animals and the environment. Finally, by the pesticides killed the insects as a natural food source of birds and damaged nature both in the production as well as the use of pesticides. The company Mühldorfer produced for many years a biological animal feed (also true for cats, dogs and horses), and I've always been very satisfied with all the products !!!
