We have had Bluetits nesting in our school for the last 5 years. When they are back we will set up a live feed.
In 2017 we had 9 eggs and they all hatched, in 2018 we had 11 eggs but only 3 hatched, but in 2019 no birds nested in our box. In 2018, we think only 3 eggs hatched because it was very cold with snow, just after the eggs had been lain. This cold weather may have prevented the eggs from developing properly.
We look forward to more eggs hatching in 2020.
