So I have 3 cats...I bet we can see what happened here! Yup, they were racing around and even though I keep my incubator well out of the way and tucked back they still managed to hit it. 2 eggs knocked into each other and cracked. It is half way through day 17 and even though I tried to repair the eggs with nail polish, one of them was cracked in such a way that some of the membrane was still going to be exposed so into early lockdown we go! I candled them and one of the cracked eggs is alive and kicking and the other is a Maran egg so I can't see squat! Either way, I have done all I can for my 9 little survivors and now only time will tell. I will let you know when the fun begins!
