May I ask how long this sack will last you? I ran out yesterday, it has lasted me two days short of three weeks, and cost me £20. Added to which I am buying a 20kg sack of Wild bird seed, and 25kg of Mixed poultry corn, and 13kg black sunflower seeds fortnightly! 25kg of Peanuts lasts about a month. I think it must be upward of £20 a week, oh plus a bag of sultanas every week for my blackbird hen, and around three loaves of brown bread!
So the most birds I have in the garden at any one time is around 14-16 greenfinches, same amount of chaffinches, about 25+ house sparrows, 8 bluetits, 8 great tits, 4 goldfinches (two babies this week!) 2 blackbirds, 5 siskins, 10 collared doves, a couple of rooks, and wait for it ..... 45+ Jackdaws! It is probably nearer 55 but hard to count the swarm. The other afternoon, there was the most amazing flock circling overhead, more than 100 of them, and I was praying that they would pass over! (They did, thankfully) They are wiping out a huge feeder full of corn (for my three chickens) and a massive bowl of wild bird seed in under an hour. And the sparrows are munching their way through the sunflower hearts.
Help!
