The soonest possible hatch date is May 21st - more likely a couple of days later, then the other two should hatch at 2-day intervals as they were laid 2 days apart.
My only worry is that the new male might drown if it takes on a pike that is a bit too big for it to lift. Large pike seem to be its favourite.
And what a fidget he is - can't sit still on the nest whilst incubating, always has to be playing with the bedding and dressing up in it!
