4 babies doing well

Just wanted to log in for David’s records that we do have 4 bluebird babies doing very well. We were finally able to check last night when the bluebirds were chasing off some other birds. We also have TRES babies. My husband could see “gaping mouths” thru the hole (his words). We can’t physically see these babies due to the numerous feathers in the box. Even a mechanic’s mirror gives no discovery. We’re enjoying the feeding show taking place on both ends of the front yard with these two nests. It’s a busy flying thoroughfare out there!
