That is good. Will your break her from being broody if the eggs are duds or will you get some fertile eggs for her to hatch?
I usually just let them sit. We have enough birds that I'm never short on eggs over summer, and they'll only go broody again. One of my Orpingtons was so bad in her youth that she'd lay about 10 eggs, then go broody over and over again.
I've put a Muscovy duck egg in my incubator from one of our new girls to see if it is fertile from her old home. If it is I might swap them out and Sunflower can raise a duck or two (which might be funny seeing as they'll get so big so quickly).
Hello Jae Oh no is everything okay or do they do that often?
DH didn't quite put their cover down far enough at the front, so I think the white cat wafted past and gave them a scare. She kind of glows on the dark which is a good thing considering some of the weird places she'll sleep (like right outside doorways). Cockatiels are prone to night frights, but that's usually the cause with our boys.
