Thank you Yvonne! You are my hero!!! I appreciate you and all your informative wonderful posts!!!!When a baby is breaking out of the egg, he actually turns around inside the egg to break the shell all the way around. Sometimes they end up on their back. I generally set them right when I see this. It's not harmful to move them once they start hatching.
For what it's worth, I have bred tortoises for over 50 years and have had a couple babies drown in the albumin of their own eggs when they were not upright when they broke out and needed to start breathing air. Hence, I would turn it upright and make sure it doesn't have any albumin in its nose by touching it gently to make it pull its head in which usually expels anything in the nostrils. You can use a Q-tip to touch the nose and absorb anything coming from the nostrils.Ugh, so conflicted! We had one in the past that pipped a good hole, we could tell he was upside down but he never fully hatched and died in the egg. This guy has progressed quickly, no sign of hatching yesterday and when I got up this morning his head and front legs are out. I'll leave him be with a constant eye. Luckily I have a good view without having to open the incubator constantly. I'll keep you updated. Thank you for the responses! You are all so helpful and I wish I had a found you a few years ago!
