I am in Woodburn between Portland and Salem and we haven't seen the sun for days. I have 2 adults and currently 7 babies about 2 1/2 months old.
My male and female are by windows they look out all day, they have both seemed "dingy" in color, but otherwise fine. Female is very gravid.
The babies can not see out side and are normal bright green, active and happy.
First don't be too worried. Much like yourself, don't go running or exercising out in it, but indoors is OK. Fire is part of nature, so don't throw him out in the thick smoke and he will be fine.
I do wonder if their is an instinct that detects the smoke in the air, meaning fire danger to them, which could add some stress.
