Hi, so I have a male blackbird that comes into my house to eat my puppies biscuits. He’s comes in eats one and takes 2 with him, he does this countless times a day probably eating more or just as much as my puppy each day! (1/2 cup per day) Shorly he can’t be eating that much each day but what could he be doing with them? I would have thought they would be to hard for their fledgling‘s to eat?
