I live in the wind belt and have seen more than one tossed against the fencing. My polish were so stupid that they drowned in 3 inches of water when they were a few months old. Kinda like in the movies where the guy that cant swim is flailing around until someone tells him to stand up and he can actually touch the bottom. Yep....I have homemade waterers now and they cant drown unless they stick their heads into a smaller space and inhale, which wouldnt suprise me with those guys. My other chickens are pretty smart and get inside where it is nice whenever it rains. I do have a couple of worm slurpers though.
I do not think that all chickens are dumb, but either the polish are the exception or we just got a batch that lacked brains. My 6 year old wanted the polish, I prefer meat or eggs, you get neither with them. However, I just bought some OEG creles and love them.
