Hi Nic, I got you :). I’m going to try some of the mix and the biscuits and see what happens. I’m thinking of trying dried calci worms too ( https://www.chubbymealworms.co.uk/collections/dried-calci-worms-1 )
My garden is a tip, perfect habitat! I don’t put that much food out, and what I do gets shared with the foxes.
