It seems we have hundreds of birds here these days. And I love it! I think they all are born under our roof and thus belongs to our family. And of course they also deserve some festivities!
I have made melted fat and thrown in whatever I had in my cupord of cereals, millet, corn,sunflower seeds, etc. Then I put it into my muffin forms,with a thread in the middle. Then out in the cold for half an hour before I took them out of my muffins forms and hung them up outside.
I have used melted animal fat, but could have used coconut fat or any other fat that goes hard when cooled down.
