Box Four Family coming along nicely

The five young hatched a week ago, and here is the mother coming out of the box. She had no food, she just wanted to check the chicks after I opened the box.

The young are fine inside. They had opened their eyes so they ignored me and did not raise their heads.

The dad is subduing a caterpillar on a post here, and brought it to the kids a few seconds later:

The female checks chicks

On the South side there are other nests with eggs and one with two young. They are the oldest chicks we have. Near feathered. The third egg never hatched:

On the North side, only Box 16 has four young, some pinfeathers but younger than the South side, eyes maybe closed.

This is their home. I put fancier numbers on these, so I can monitor the ones in the middle easier. I do not open many swallow boxes. But none had hatched. Too cold for a week.
