Candled my 100 eggs last night and this morning on day 14. Threw out 15 clears are stopped developing. Down to 85 now. Lockdown Thursday the 13th and hatch the 16th. This is going to be another staggered hatch. They are all developing at different stages. This happened with my last hatch. Took 5 days to hatch all the eggs. Any ideas why this happens?
