My eggs are scheduled for lockdown on Wednesday, however I think they may be falling a little behind on development. When I candeled them last night you could see that a chick was inside, however, there is still quite a bit of space at the bottom of the egg. The air pocket looks great, but as I stated still some space at the bottom. Is this normal or are they slow? There was movement of something so I believe they are alive. Can anyone help me? Thanks in advance.
