First off, I should add I ended up going out there in the wee hours (1am ish) and they were all still there looking like drowned rats and seemingly miserable. Feathers parted from being so wet, standing and shaking out, etc. So I said forget it and tossed them inside leaving the bottom cracked open so they could squeeze out when they woke up and came downstairs. Their coop is inside a fully fenced garden and that sits on a fully fenced acre.
When I went back to check on them about half an hour later they were all cozied up together and grooming the water off each others backs.
My chickens are about 9 months old (we got them in January listed as 18-22 weeks)
This is my girls ' exact coop, they all fit comfortably on the roosting bar but one often gets down in the night and beds down in the shavings.)

We're building a new, larger coop from scratch that should be done come Memorial day!
We live about 25miles North of Seattle.
It's pouring, like hear it on the roof, windshield wipers on full, quite often this time of year and about 48- 54 at night and daytime vary wildly from low sixties to mid eighties just last weekend. Our weather for the next several days is rainy and low sixties during the day.
Thank you!
