NATIONAL TRUST DUCK & SWAN BLEND, £2.50 FOR 1.5L/900G

Ducks and swans need more than bread. This blend is, apparently, tasty and nutritious – eight out of 10 ducks prefer this to other blends (I made that last bit up by the way). It’s a mix of barley, wheat, dried grass pellets, linseed and more. Throw it at the waterside or on the water (it doesn’t float though). Sales help the National
