Our NUGGETS "plus" can be fed alone on a platform feeder or Nugget/Peanut/Sunflower feeder using 1/3" wire mesh. To adapt bluebirds to this food source: start by putting a small amount of Bluebird Nuggets on the feeder ledge. Once the birds discover the Nuggets, move them inside the feeder. NUGGETS "plus" may also be blended with 5-10 lbs. of your favorite wild bird seed mix. This mix may then be fed from tube or hopper style feeders.
