Waiting nearly over?

Our birds this year have had to put up with some very wet and cold weather.  Hopefully everything's gone OK and we may have some chicks at the end of the week.  Our pair have never managed to hatch all four eggs, and it will be a miracle if they do this year – especially with the weather and the egg spotted by Bob that was left uncovered for a long period on 8^th April.   Our birds are lucky in that they have been sheltered from the east by the spire.   Unfortunately today's incessant heavy rain took its toll on two of the four chicks at the Nottingham Trent Univerity site (they are two weeks ahead of our Grantham pair), despite a very valiant 12hour constant effort by the female who was absolutely soaked to the skin as she tried to cover them and shield them from the rain.
