While clearing out a gutter of leaves just now it was realised that one of the 'bundles' of leaves removed was actually a robins' nest with 3 young birds in. :-( We don't think the young had left the nest previously. The nest has been put back in the gutter with one of the young who has since hopped off. One of the others appears to have been limping. The parents are still around and feeding them. Please can you advise what else we can do.
