I need advice regarding a nest box on the back of my property fixed to brick at a high level containing a Great Tit family. The chicks are around 5 days old as at 19-04-2022.The nest box has been in position for around 3 years. This year and following major works on the properties with scaffolding (most of which has been striked), I noticed that the nest box is damaged with the top and side panels coming away. As the chicks grow, the weight could losen one of the wooden sides and the entire brood could be at risk.
The nest box in question is in Forest Hill, London, SE23
