Three eggs in the bedroom nest today. Looking back the third egg was laid on the 25th last year in that nest. In the end only two hatched but both fledged successfully. I am sure there are eggs in the chimney nest as there is one of the swifts on the nest all the time. The straw round the nest makes it impossible to see in the nest so I have no idea how many. No sign of any activity in the attic nest. I think the single swift was out all night.
