Based on all of the data that I have, egg 3 should arrive between 2:30 am and 11:00 am Wednesday. Using only numbers for the current female, that narrows to 2:30 am to 6:30 am.

This was an unusual interaction. The male arrived to take over incubation but the female didn't leave. After 36 min on the edge of the box, she got back on the eggs.

A very early changeover at 3:31. Note the egg nearest to the camera. This is the one that is probably not viable. It is moved very easily, suggesting that the contents have dried out.

Wakefield's first female peregrine fledged 29 chicks in eight seasons, i.e. an average of 3.6. Our present female has fledged three chicks in three seasons, giving an average of 1.0.

We now have four eggs. Counting 34 days from the laying of the third egg gets us to Tuesday, 28th April. This is approximately when we expect hatching to start. One egg appears to be damaged and that number could increase if the female carries on being as clumsy as in this clip.
