Subsidence

I thought that the baby blackbirds must be getting big now because Mr Blackbird appears to have de-wormed my entire garden in the last week but I was not expecting this when I peeked into the nest ... babies with real feathers and almost full sized!!

The downside is that the nest has serious subsidence and appears to be about to fall out of the tree.

Any suggestions welcome ? I?m worried they fall out as they?ll surely die but if I try to do anything the parents will probably abandon the nest.

Strange how you can become somewhat attached to creatures that you consider pests at other times!!!
