Great Crested Flycatcher abandoned eggs

Sadly these eggs seem to have been abandoned, I noticed a lack of activity at the box for a while, upon opening the box the eggs were stone cold.  I candled them, did the float test, and as a last resort opened one egg.  No luck. I was looking forward to the fledglings, but more importantly, I wonder what became of the female as the male is seen on occasion.  It’s a hard life being a bird. The nest was made up with animal fur, different feathers, a bit of what might have been snake skin that Emma put on the fence, grasses… all nice and soft.
