So i let my chickens out this morning and about 30 minutes later it started to down pour! and as soon as i saw the rain i began to run home to put the chickens in side, but my father in law said it was not big deal, they will naturally seek shelter.... but when i can home for lunch, my two girls where still outside soak right through. is this normal that chickens will stay in the rain or do I have chickens with a duck genes?
