Remember we had an egg this season that did not hatch. Finally permits were granted and the egg was opened. It appears it was never fertilized so no hatch. This is the first time for this to happen at this nest, but it is nature. They found a lot of nest material in the nest cup area where they found the egg buried deep. It is believed just the nest cup material would fill a 5 gallon bucket. We knew the cup was deep but not that deep, so just how deep is that nest and where do those mice live in the bottom of the nest.
More from the RRP blog on why the egg may not have been fertilized.
