I am looking for recommendations for wild bird seed with no waste - we find so much has been dropped below the bird table, which could attract vermin. If we had a saucer under the feeder then the wasted would just fill the saucer. I am assuming the waste is husks after the birds have eaten the seed, or perhaps the manufacturer has added filler to bulk up the weight. It just seems so messy and a waste of our money. Where and what do you use or do you have the same problem?
