Slow development?

[oinkpiggieoink]

It looks like my eggs are developing really slow. Like they are a couple days behind. They have never shown any sign's of being quitters. I never see movement either, is it possible for a egg that is developing slowly to survive? Thank you.

Yes this can happen with lower temps or if the mama hen gets off the nest and comes back letting them cool down (if they make it). Of course it can decrease the % that make it.

Make sure your humidity is OK.

I hope this helps.
