Peregrines at Wakefield Cathedral

It was 3 last year, but one year they did have four eggs, but one of the falcons broke it, but all hatched & fledged successfully. In the past, there has been one egg laid the day after the first one but a couple of times, it's been 2 or possibly 3 days before the next one. I'm assuming that this pair will definitely have 3 eggs though.
