Still here Pete, spent the night under a tree with mother duck - and there in lies a problem, as duck poop will stain the new plaster if we allow them to stay.
We will be contacting the local animal rescue place to see what they can do to repatriate them
I've no desire to sound cruel because I love animals, but these little tikes will make a big mess, Chris. (I've been through it.) I'd encourage them to migrate as soon as possible if I were you.
