I have gone over to the green side chaps and I must say it's the rite thing to to, please don't be ugly to our little featherd friends, they just crap when the need comes and is not intensional.
Here are a few examples to keep our friends out of your nasty hanger.
1 Build a nice bird bath outside and make sure the have running water and fresh food.
2 Build nice cosy nests for them on the outside but under roof, make sure cats and snakes can't get to their nests.
3 Be kind to our friends, if you see one lonely little bird in a tree, walk up to it and speak to it, explain to it to stay out of your hanger.
4 If a young friend falls out of its nest gently pick it up and put it back in the nest, remember what goes around comes around and that bird will never crap on your wing, never.
Hope this will help all you nasty's to turn good, like me
