HELP my ducklings are gutt loaded full of food throwing up

[Icravepoultry]

My 2 month old runner ducklings have a full crop and throw up green gooey clumpy liquid.
It is closer to their neck
When they are fed it is a pile of food and they just stuff it in like crazy but i didnt think it would turn to this

I am not sure I understand the details here.

I can tell there is a big problem - but trying to sort it out. So let me ask a few questions.

What are they fed, and how often (include treats or things they might forage if they go outside)? Have they been given small quantities of chick-size grit?

Is there a strong smell to the vomit?

Are they pooping?

When did this start?

Do they go outside?

Are there other animals around?

What is the temperature in their brooder?

Do they have water 24/7?

They have lived outside since they were 2 weeks old and live with chickens and goats they have access to a pond 24/7 and are fed chicken food once a day and have an acre of pasture

How many do you have? Do you have a good duck vet?

It could be a number of things - they could have gotten into something poison. If that is the case, they need a flush and food grade charcoal slurry, and lots and lots of clean fresh water.

They could have picked up a bacterial infection.

They could have eaten something that is stopping up their digestive tracts.

If it were me, somehow I would get them into a clean area, with plenty of fresh water and good quality food. I would get them into a tub of lukewarm water so that I could get them cleaned up, and observe them. What does the vomit smell like? If it smells yeasty, they may have a yeast infection.

I would keep them separated, in the clean area with plenty of fresh water and good quality food 24/7. Ducklings, if they don't have food often enough with gorge themselves when food is available, then throw up.
