Well it looks like we're down to 3 birds. They're fattening up a little and have more feathers. The nest is so small, I can't imagine how much bigger they can get and still live there. You'll notice they've pooped all over the front door so I'm not as in love with them as I was. Bird poop is pretty gross....on my front door, even grosser. I think next time I'll be a big meanie and get rid of any nests I find in my door wreaths.
