Hi- we have a blue tit nest box on the wall of our house, currently occupied by a female who has laid 9 eggs- she doesn’t seem to be supported by a male and sits on the eggs for about half an hour at a time before nipping out for a few minutes to feed. We have had scaffolding up for about the last four weeks to have our roof relaid- the nest must have been built during that time, and the bird doesn’t seem to have been bothered by the builders- but the scaffolding is due to be taken down later this week, with lots of to-ing and fro-ing past the nest box with scaffolding boards and polls. Is this likely to disturb her, and is there anything we can do to avoid this?
