Both Donna (in Box1) and Rosie (in Box3) have stopped laying any more eggs and are incubating. Donna appears to be sitting on 10 eggs, and Rosie on 8.
Here is a picture of Donna about to leave Box1. You can clearly(?) see 10 eggs - well perhaps I should have said probably see 10 eggs.
This one is a bit better. I have (almost) no doubts about this being 10 eggs!
Now this time there can be no doubt at all. Rosie has (at least) 8 eggs in her nest.
It is interesting that this year, both Donna and Rosie laid two more eggs after they had started incubating. They both started incubation at about 3.30pm, Rosie on the 29th and Donna on the 30th April.
They both laid an egg the following morning, which we expected, and then one more the after that day which we did not!
It will be interesting to see how close together the eggs hatch. Hatching normally starts about 12 days after the start of incubation, and this would imply the 11th and 12th May respectively.
