The bird is free! He (she? How do you sex a chick, anyway? No, wait, smartasses – don’t answer that.) must have made his way out of the wall overnight. He was sitting on the floor in the basement this morning, so I wrapped him in a towel and took him outside where he hobbled into a patch of vinca. I have no idea if he’s injured or just can’t fly yet, and no idea if he’ll survive outdoors, but at least now he’s where he should have been all along.
And I can stop being upset about the poor thing.
