Duckling has a pea stuck!!

[Vienna blossom]

One of my couple day old ducklings swallowed a whole pea the rest of them were broken up so there was no problem but he can’t seem to swallow it! He can peep but he won’t stop trying to swallow it I opened his mouth and i can’t see it I also can’t feel it, I’m not sure what to do? My worry is he won’t be able to eat or drink properly unless I do something, he has mucus coming out of his mouth from struggling to get it down

Can you post a picture so I can get an idea of how big he is?

It's probably stuck in the crop and can't pass though.
Massaging the crop might help, though be gentle.
Don't give them any more treats until at least 3 weeks old

Ducks need grit in their crops to digest anything more than crumbles. The pea will hreak up and be swallowed but not as quickly as a pea in a crop containing grit. Before you reintroduce peas, please get some small chick grit and offer it ina side bowl to the ducklings crumbles.

For now, do encourage drinking: ensure full access to water to drink
