The first eggs are usually laid at the end of May or sometimes in the first week of June, but this can vary depending on the weather. Both sexes incubate, with the eggs taking an average of 19 or 20 days to hatch. The clutch is two, sometimes three, with incubation usually not starting until the clutch is complete.
