Cat, as a fellow 'ertfordshire ,edgehog" I have to disagree with this "Established Wisdom" that pigeons have to feed each day. When it's warm like it is now, if they fluff up a bit and don't fly much, the odd mouthful of berries or rape will do them just fine. I've shot a few (very few compared to last year) and NOT ONE has had a crop FULL of anything, just snacks.
We DO need it to get cold, then the need for fuel will increase, just like us OAPs!!
THINK SNOW!!
