Hallo to you all from a very very wet Wuppertal in Germany, they have a saying here that all babys born in Wuppertal have an umberella in their hand when they are born, but that has absolutly nothing to do with my question !. I have built a robins nest box, you know the type.. with an half opened front instead of a hole. I have clear varnished the outside of it and also put a slate on the roof, I was wondering if I should also varnish the inside of it, or would it be harmful to the birds...that I hope will nest in it next year?. Thanks for any answers.
