Thank you dreamtree. Very kind.
TL that is what I am trying to do. I am delighted to say that I put a cooked thin slice of shredded runner bean at the nest entrance- the edge poking into the nest room. A few minutes later it had gone. I don't hear him even from a short distance away. I just quietly lift the roof of the outer room and can see if anything has gone. The small pieces of peanut are there or possibly one gone. It may just have gone down in the fitch.
I will put porridge there later on. Can't expect him to eat too much at once.
