I have filled the lining in my birdhouse with feed silo. The food I have had for about 1 week in operation. Every day I see after the feeding stall and the silo is empty, the food is still scattered in the bird house. At the bottom to the aviary around, always cavort many finches and house sparrows. In Futterhaus I keep seeing tits and sometimes greenfinch.
Conclusion: I guess that the mentioned groups represent consumer of the food, from the lining alone can not slide down in the silo (fireplace). Thus, the feed fulfills its task.
