Hi, we seem to have blue tits nesting in our box. The female today hasn't left much so I think we may have eggs. My worry is in two weeks we have garden work being done. I'm worried the noise and men working will scare them off as it will be around the nest box. Will this make the nest fail
It's certainly highly likely, could you not put it off until you know the youngsters have fledged? They only have the one brood ... Some info on timelines here ...
