2 today. One from Dove at 46 grams, a 52 gram one from Red.
I thought it would be 3 but The Nuzzler was in and out of the nest, panting, going pale, adding feathers and nesting materials, turning round and round, then decided to drink a bunch of water, take a couple dust baths and preen. She seems to have forgotten all about laying her egg for now.

She hasn't stood her tail all the way up all day and I know it is coming soon.
I was in the run just sitting back and observing for more than an hour... Silly me.
