Ok, today is officially day 21. I know egg sitter eggs dont hatch on schedule. I candled the egg last week and saw a baby moving all around. Today while momma was off her egg I candled it. I no longer see a baby moving around but a solid dark mass and the top of the egg has a bubble. I dont see any movement or hear anything (if I'm suppose to I've read you can hear) Is the mass a baby that is too big to move so it can be any time now? Whenever she gets off which is once a day and I have to catch her so I can see if there are any cracks. This is so nerve wracking and exciting!
