YaaaaaaaY!!!!! CONGRATS!! My Frankie squatted 6 days before the egg arrivedThat sounds like it. About your other question, couldn't have answered it until about 30 minutes ago - just got FIRST EGGGGGG! SO EXCITED. I noticed first squat almost five days ago. This is my first "first egg" so I don't know if that's average or not. She laid it in the nest box right next to the ceramic egg.
