I checked in on our houseguests last night to see if there were any changes. I found one little guy had hatched and two eggs. I’m not sure what happened to the other two. There were still 5 when I peeked a couple days ago.
Here’s a photo. The lighting wasn’t great and I was trying to be quick (momma bird was watching and I need to water the basket as well) so it’s a bit blurry. The little guy is laying over his sibling eggs. His beak is hidden behind his head on the left side. He looked up with an open mouth when I first peeked.
