We all love to see those birds flitting around our bird feeders, but when was the last time that you cleaned your feeder?  Regular cleaning of bird feeders is necessary to keep bacteria from building up, which could make the birds sick.  Old, stale food in a feeder may cause birds to stop visiting (would you go back to a restaurant that served stale food?).  Also, don't forget those hummingbird feeders. Hummingbird food will go stale after only a week in hot weather, so don't forget to refresh hummingingbird feed.  Spencer's carries a full line of feeds for our feathered friends.
