Our little birds started hatching Saturday morning and by this morning, all 5 had hatched. And they aren't wrens afterall. Bill got a good look at both parents and they're Purple Finches.
The babies are currently kind of scraggly looking but I'm sure they'll cuten up as they get fluffier and fatter. We don't want to take too many pictures of them because we don't want to bother them too much, but we'll post updates as they grow.
