Poults 2 weeks old, vomiting, tired, swollen chest

[Chstiina]

Hi!
I have 4 turkeypoults and 3 of them is sick.

One of them were sick a week ago, vomiting, tired and slept all the time, but became okey after a couple of days.
But now, a week later the same poult + two others are very ill.
They throw up when I lift them up, it almost "rains" yellow thin fluid out of two of them. The third poult is the sickest, the vomit is thick slime, maybe a little bit grey.
Their chest is swollen. They are tired, the sickest ( not the poult from last week ) have slept the whole day today.

The poults live in our house so they haven’t been outside yet.
They eat pellets for turkeypoults (starter?) which I mix with water.
They have clean water all the time.
And they have gotten gras until yesterday.

Why is my poults sick? Can they be constipaded? Our vet doesn’t "do" turkeys so we dont know what to do :/

I've never had this happen before, are they eating and drinking? try to pick them up as little as possible, especially if there not eating. have they been passing? if not you could be right. make sure to separate them. with the sleeping one, try giving antibiotics if no one protests. I say only to do it with that one because its condition seem dire, its likely to die untreated. I'm not sure if the antibiotics are the right thing to do, they could make it worse. also check them four poultry lice. if they don't dust bath and are sick its good to know if they have the white creeps or not. poultry lice is crazy tiny. also stay with her, she's probably going to die. and bring them outside once or twice a day, that way they have the chance to dust bath and forage if there not to sick. also bring them to a plce with grass and tiny rocks and no pesticides.
