My blue birds only had one brew this year. I know they had babies because their nest was broken way down. At the bottom buried deep in the straw, I found this little egg that never hatched.  The photo tells a tale that is sweet but also sad. Usually they have up to three sets of babies, but not this year, and I’m not sure why. Maybe they are still adjusting to their new digs, which includes a  secure entrance way that helps to keep predators out.
