These eggs look like they have fully developed but the outside of the shell is getting darker and i can see a baby inside but I'm not sure what's going on with them not hatching. Do you think they are dead? They don't smell any. Any clues.. Ideas..?
I'm in the same boat. I have a Brinsea Mini Advance and set 7 eggs. Day 7 it was obvious two were clear so I replaced them with chicken eggs. 1 duck hatched day 27, then the next day the chickens hatched (was day 21 for them) but nothing from the rest of the ducks. Today is day 30. How long should I wait?
