Hello - I'm taking the plunge and getting a coop and three chickens for our garden (arriving next week). They're going to have about 7.5 square metres of run, which I'm planning to cover with woodchip (possibly with sand underneath, as part of the whole garden redesign involves getting rid of the old sand pit). They'll be able to free range when someone is outside with them, but most of the time they'll be in the run, as I don't want to sacrifice the entire garden to them.
Unfortunately, dh is very anxious about the potential smell (he has a stronger sense of smell than me, as bad luck would have it). Any advice for what I might be able to do, or to tell him, that might give him some reassurance?
