Broody chicken can’t poop

[Caz777]

Hi. Please help
My broody girl is sitting on duck eggs and for the last 3 days she hasn’t done a poo when she gets up to eat and drink. She stands there like she is trying and a squeaky air sound comes out her vent. Is this ok or should I do something. She is not eating as much as usual and she has 5-6 more days until ducklings will hatch.
Thanks for any advise.

Check her crop-is it emptying overnight?

I think I would get her hydrated, sounds like she may be constipated. A teaspoon of coconut oil twice a day may be helpful as well.
