I have 9 fertilized duck eggs. We didn't have a incubator so one of our chickens has been sitting on them. Our first duck hatched prematurely and "passed". My mom caved in and bought an incubator last night that controls temperature and humidity. One of the ducks in side the egg has been pecking on the inside of the shell for two days now. It stopes last night and it wasn't moving this morning. I'm hoping it's just the "resting stage" where they absorb all of the yolk. The temperature on the incubator is set for 99.5 degrees F and it produces the humidity by little areas in the bottom where you put the water. I guess what I'm asking is do my ducklings even have a chance? I have two more that are pecking at the shell from the inside. Is the shell too hard? I know not to help them but I don't understand why the one isn't moving anymore. Thanks.
