It's day 2 of lock down and I look in window and I see this egg. I had to open to take it out, I've been hatching eggs for at least 10 yrs now and I have never had this happen. It's my second time using a brand new hover bator and you know, my old one is more reliable! This egg did explode cause it was on one side of the bator and I found the top on the other side and the yolk looks cooked ( obviously unfertile). The temp is at 99.8 Does anyone know what would cause this?
