I ordered last winter handmade bird seed, but oh dear were the usual Meisenknödel holder all too small or too tight. Then I found this feeding station of Gardman and my problem was solved. Is expressed using the commercial bird seed from the hardware store, the turn out all slightly smaller, then you can easily have the Knödelboy, feeders for chickadees Erdtmann of use (available at Amazon). This is even preferred by the birds. I think because they are better able to hold on to the closely meshed grid and enclose the fat dumplings also close.
