This is my first time hatching eggs. I started off with 16 eggs. Day 5 in the incubator I Candled them and 5 were duds and 11 were fertilized. I candled again on day 7 and all seemed every egg had movment and seems healthy. I canadled again today which is day 11 and 5 eggs were for sure ok 6 didn't seem to change much from day 7 and there was no movment in the eggs, there was just a black spot about the size of a nickel. I decided to open 2 of the 6 eggs that didn't change. There was a baby bird inside both eggs but I'm pretty sure they were dead. I decided to put the remaining 4 eggs back into the incubator just in case. What would cause them to die? The temp in the incubator has been pretty steady at 99.5 - 100.2. Should there be movement in all the healthy eggs? If there is no movement would the eggs be most likely dead? The 2 eggs I opened there was no movement at all from the little chicks that were inside.
