On your own for the next 10 days! And some confusion.

I'll be leaving the birds on their own for about 10 days. There are some eggs around, and in that time something will come of them or not.

South side: Box 4

Box 2 was checked, it still has four eggs. they will hatch any day now. Box 4 had the four young as last time. The eyes now have slits that will soon open. If they hatched on the 7th, the eyes will open the 13th, tomorrow.

Box 7

Three young are developing normally. They too will open eyes soon.

Box 10 

This was the confusion. I opened it twice, once getting a photo. Four tree swallows attacked me the whole time. I had to go home and check on photos of them. Are they bluebirds? Here they are earlier, one still an egg:

And here they are now, ready to fledge. Yes they are bluebirds, not swallows. The swallows just hate me for opening their box earlier.

North Side

The pair in Box 13 are still working on two eggs, now with wren guard in front. The two eggs have been there 5-10 days, I do not know how many days past 5.  The wren guard is still in place and the female was inside.
