So, a few days ago I noticed one of the eggs in my incubator moving a bit. It wasn't much but it was noticeably rocking. This has been going on for three days now.
I know that ducklings need to adjust themselves in the egg before hatching but is it normal to take a few days to do so? I've never had any ducks take three days to pip so I'm a bit worried about whether it's having difficulties or not.
Please let me know if you have any ideas.
