New chicken mommy! How common is it to have covered chicken runs? Our run is about 25x35 ft. I've only had the chickens for the winter so I'm getting really excited for the summer. I know how much they like to be outside when it's nice out now, that I'm dreading locking them in at night in the summer. I'm debating whether or not to revamp the run to cover it so I can leave them out all night. Thoughts?
