We live on Whidbey Island in the Pacific Northwest, right in the beautiful rainy Puget Sound. Most of our chickens stay out in the rain (Cochins, Wyandottes, Rhodies, Marans, etc.). We've set up the roofing on the rabbit pens so there's overhang - they like to perch on the top fence rails during rainstorms and supervise the rabbits. We also have roofing over the pens, which they won't go hang out in during rainstorms - I used to lock them in the pens, but there just wasn't any point, it just made them cranky.
Our Silkies have a roofed pen, I'm not letting those out. The phrase "too stupid to live" comes up a lot around them. We had to rehome our Polish, I swear she was suicidal - she'd get up on top of one of the doghouses right under where the Bald Eagles like to hang out!
I figure if the big standard chickens can handle a rainforest like our area, they can handle just about anything.
