Bust day with grand children but before they arrived counted 9 swifts screaming round the house while one was on each of my nests so that’s 11 in total. Most of the morning groups were screaming round the house. A busy swift day. More good news. Can now see 2 eggs on each nest. Only managed a photo of the eggs in the chimney nest. All have now returned to their nests so will try to get a picture of the bedroom nest eggs.
