Questions about broody hens

[Glenmar]

My hen is sitting on 15 eggs. I am sure the other hen contributed to that. The first day she was on the eggs, she got off at night. The second day she was on for good. Will that little interruption in sitting in the beginning of incubation hurt the hatch?
What are the most poults your hens have successfully hatched at one time??
This is her first time.

Sounds like it is common. Maybe it will not cause a problem.
