Hi all. We have 13 eggs in the incubator this time around. They're due to hatch this weekend. I did the last candling today before we go into lockdown and found something odd. Many of them looked like typical almost-hatched eggs. Very little space in the egg, big air sac, etc. A few looked like they were only about half way through the cycle! But two of them I candled actually moved! Very obvious movement. Is this... possible? They were all put in on the same day. Some were older eggs and some were fresher but would that make a difference? Should I leave them in there extra time to see if they keep growing or are they probably retarded and won't hatch/live anyway?
