I am going to run out of sun flower seeds for the birds. Do you think alfalfa pellets would hurt them? I am not driving to town in this cold. I am going to move the cat food to the barn where it will attract opossums because they are eating all my cat food. I have a bunch of birds here and they were hitting the window this morning. I put my jelly like Christmas window clingy things in the window to reduce that. They are red clingy cardinals and holly leaves.
