The shelled sunflower seeds are all birds that land on my balcony, very popular. In contrast to the previously used "normal" seeds with shell almost no residues remain here (apart from tiny pieces that fall). Contrary to popular view is that food here all year hotcakes in birds.
Since I bought these seeds for the 3rd time, I was a bit disappointed with the last delivery. Before there were recognizable cores, were in the last delivery almost exclusively fragments.
