Chickens acting weird...

Awesome! A topic about chicken behaviour. I've been waiting for a topic like this for some time.

Anyway, I think chickens are just dumb. They probably don't realise that if they go inside it will be better. They probably can't think ahead. I was watching half a dozen pigeons a few days ago getting absolutely hammered by hail, and if they moved only a few meters to the left they would have been sheltered, but they didn't, they just sat there.
