They have either flown, or died somehow. Don't you think you should get it fixed now?
We have a vent for our shower that extracts the steam, the opening on the house for the vent is broken and we have had birds in the past that have used it for a place to nest. Recently we have seen a blue tit flying in to her babies (we cannot actually see the nest) and have heard them chirping whenever there is movement in the bathroom. I have heard them chirping on and off for the past few days but have not heard them since around 2 days ago. We don't think they have left the nest as it seems too soon, any ideas on why we can't hear activity? :(
