First time hatcher, and I have 9 surviving muscovy eggs out of 18. Or at least I think they are surviving. I'm on day 36 and no signs of hatching. Some of the eggs are getting dark spots and I don't know if that's a good sign. I'm working with a hoverbator with an internal fan. If all of them are dead when a week ago they were moving around in the eggs, what would be the possible reasons they died? I've done everything the instructions told me with some help from others on this site, why would they die? Help.
