The smell may be a relative thing too. We have a friend who comes over with a very sensitive nose. To him the smell from a from a recently cleaned brooder box is over powering. I had 4 2 day old chicks in a rubbermaid in the spare room and he wanted to know how we stand the "stench" LOL. I've known him for a long time, he's not being rude, he really just has a very sensitive nose.
