The Nottingham group are a bit older than the other two groups, but the parents must go off to hunt and the chicks aren't too active yet.
I imagine one of the parents might have been keeping an eye on things from a distance and I doubt anything would touch the chicks
Before too long you'll get hooked on the osprey babies as they come along and at the end of it all, you'll wonder where your summer went, but it's fascinating and absorbing so enjoy !!
