They have a lot of shade from the trees, and I keep the big coop door open day and night (don't have a problem with predators, just neighbor's dogs getting loose). I also put out ice bottles for the flock to lay against if they get hot (also do this for my rabbit).
I would lock them up at night if they don't have a secure run, it's only a matter of time before a predator comes along. And loose dogs are a big problem. You can add little windows to your coop with welded wire screwed over them. Don't use chicken wire a coon can chew through it and don't use staples they can push them out. Just trying to help hate for something to get in one night. You would sleep better

Hens go broody when you don’t want them to… and won’t go broody when you do.

I scare myself thinking I'll forget. If I have to have my daughters do it I'll call them and remind them when it's almost time and then insist I get a call when they are all in safe. Good thing their cell phones are attached to their hips.
I'm in Hermiston and have some pretty little seramas that need homes. 2 roosters and a trio (a roo and 2 hens). I'm also looking for silkie laying hens if anyone has any between Pendleton and the Seaside, OR area. Pictures of the seramas are below.
