Up until yesterday the swifts were out of the nest for most of the time. When the weather is warm they seem happy to leave the eggs alone. The last two days have been cold and wet so there has been one swift on the nest all the time swapping over from time to time to feed. this picture from the chimney nest 2 days ago shows, I think 2 eggs.

Then today at one of the many change overs I got this clip which I think shows 2 eggs in the bedroom nest.

I will only check if they are both out.
