Should I stop turning the eggs?

[DecemberSpices]

My chicken went missing, turned out she was sitting on eggs. Not how long she has been sitting on them but she passed so I took the eggs inside to the incubator but I'm not sure if should turn them or not. The babies in the eggs are moving around. Is it better to stop turning them later or earlier? To me they look about 15-18 days but I'm not sure.

I don't think they're as far along as you think they are, but turning is really only critical from day 1-10, so I'd say that they are definitely past day 10 and it's safe to not turn them. Sorry about your hen
