A friend is giving me 4 small-breed chickens (sorry, can't remember the breed), so I'll be building something for them in my back yard. I have a covered deck that's raised about 3.5' off the ground. It's fairly big - about 6' x 30' in an "L" shape. I'd like to just build some nesting boxes and a roost under there. The deck is trimmed out, so while there are small (1" or so) gaps in the siding around it, it's pretty much enclosed save for a spot for me to get in under it. The back yard is fenced and the chickens will have the run of the yard. Here's my question(s): Will the chicken poop from the nesting boxes and roost stink bad enough where we'll notice it when we're on the deck? I live in Spokane, and the winters are typically pretty cold, so do I need to build a coop around the boxes, or because the deck is pretty much enclosed, will a heat lamp work without a coop? I can build a door where the opening lets me go in under the deck if I need to. I'm looking forward to the eggs, but doing it more so because my 8 year old loves her friend's chickens and really wants some of her own. Thanks for any advice and suggestions.
