I've got 7 eggs in my new Brinsea Mini Adv: 6 Tolbunt Polish & 1 Isbar (bonus egg from breeder). I've had a lot of problems deciding whether the Isbar is alive or not - can barely see through the shell - it's darn thick & dark in there! And I'm using a Brisnea ovaview candler too! But today, I think I see movement! The Tolbunts have been quite active from early on - lots of movement. 1 of them was either really resting hard, or has recently expired - time will tell, but there was no movement at all in 1 of the eggs & there had been a couple of days ago. 2 eggs were chirping - so that means they have internally pipped...correct? I used to hatch parrots a long time ago, but it has been ages & I have slept since then. The mechanics are the same & theories are similar but there are significant differences as well... So, I filled both chambers; put some non-skid rubber drawer liner down for hatching; and now we wait. I guess I better get the brooder out & set up too!
