My bluebird eggs are taking longer to hatch, is this because of the cold weather? Will they be ok?
Yes, sometimes eggs will take longer to hatch if the weather turns colder. Fourteen days is the normal incubation time, but I’ve had eggs hatch after 18 days and maybe longer, though I don’t know exactly how much longer. Sometimes, however, bluebirds will abandon their eggs. A couple potential reasons for this: death of one of the adults, or severe cold that forces them to forage for longer periods of time. I would continue to wait for the eggs to hatch. If possible, watch the nest box and surrounding area for signs of the adult birds. Hopefully you will see activity.
