No more eggs have been laid in this nest since Saturday, so it seems the mama is finished and just waiting for the babies to come. I'm still wondering about the first egg laid, when the other mama was on the nest, and if it is still viable. The last time I saw her on the nest was last Thursday morning. I don't know if she was on the egg at all Thursday night, nor do I know when the second mama arrived. My first sighting of her was on Friday morning.
The first egg is due to hatch next Wednesday, April 25. Usually all the eggs hatch within a 24 hour period. Since there were two days between the laying of the first and second eggs, it will be interesting to see how that goes.
