What's stealing my eggs?

Also, I'm in the PNW where ravens are the size of dogs. I have a nesting pair right now probably feeding their chicks. So far they haven't bothered the birds.

The hens free range all day on about four acres. They lay in different places but mostly in their coop which is a secure shed. They get locked up at night and let out in the morning. The egg were being stolen the daytime.

BUT I’ve solved the mystery. Someone witnessed the thievery. It was ravens. I was leaving the main door to the coop open and the ravens were walking right in and stealing the eggs in their beaks. I’ve since been closing the door and just leaving the small chicken sized opening open during the day and it’s mostly solved the problem!

Ahhh...I was going to suggest maybe ravens or blackbirds.
Hopefully they don't figure out the small door.

I have ground squirrels taking up to 9 eggs a day. Not happy.
