A couple of our boxes have hatched out and 3 more should hatch any time now.
Merganser nest hatched out, only 4 hatched but the eggs were a mix of Woody and Merg eggs in the box and I'm sure the timing of incubation was all screwed up. Highest egg in the group rt centre looks partly broken, turns out to be an oddity for us.
There is another egg inside the outer shell!
