Setting Call Duck does she need bath water?

[Feathered Wings]

I just sat my white call hen she is on 10 eggs doe's she need a small container of water to bath in and for humidity for her eggs.
Weather being as cold as it is I have only put in bath water in with my calls on the warmest days

She hatched ducklings last August and had bath water every day thats why i was wondering if she should have it now.

Yes, she should have a small bowl of water so she can bathe in, and bring some moisture back to her eggs.
