Hi all, sorry to be off topic, if you only want plant-related discussion, read no further!

Over the winter I've regularly been making a birdy mix for the garden with crumbs, old cake bits and mostly bacon fat from the grill. But I have a vague worry - I've heard that birds can't process salt and I wonder if it's possible that salt from the bacon stays in the fat?

Is this an irrational fear? Am I being daft? Or should I stop using grill fat and stick to the Crisp n Dry?

Incidentally, the birds love it and the garden fills up within ten minutes of it going out into my wee hanging containers.

Any opinions appreciated! Thanks, Bob
