I don't think 25p is too much, not with the way everything is going up these days. Every day I put out a large plate of food for my birds, consisting of dried mealworms (the blackbirds love them), suet pieces, nuts and cut up bread (the sparrows always eat that first). I also put monkey nuts out for my resident squirrel and I love watching him carry them off. I make sure I never run out of anything because I don't like to disappoint them in the very cold weather, and it is very cold today.
