Duck keeps opening mouth and extending neck? Help?

[Juliuszcezary231]

I know this isn’t a chicken question, but maybe someone knows how to help. One of my female Muscovys has been opening/closing her mouth as well as extending her neck pretty frequently. I will attach a few pictures of her doing so, she has been eating and drinking just fine, it isn’t hot where I am so she shouldn’t be overheating, does anyone know what this might be?

It sounds like she is adjusting her crop

Should I be concerned? She’s doing it repeatedly for a while now… it’s been over a day now and we do not know what to do. Is there any precautions we can take or can we do anything to help her?

She might have something stuck or something like that. I wouldn't worry.
