Worried about chickens after using Sevin Dust

[stac545]

I dusted the run yesterday with Sevin dust and let the chickens out this morning, immediately they started throwing up the water they were drinking. I started to panic and gathered them all up after i noticed this and put them back in the coop that isnt dusted. I am really worried about them since I have never done anything like this and probably wont again. They arent acting different other than spitting up their water. Are they going to be ok? I have clean water and food in their for them to drink and eat.

Has anyone had anything like this happen? I did alot of reading on here about using this but didnt hear about any adverse effects.

Perhaps they were ingesting it? It's been standard treatment for mites/lice for years, but as a dust on the birds, along with cleaning out the coop.

I hosed down the run but im still concerned about the chickens. I just was wondering if there is anything else I need to do so I dont lose any of them. Would I need to wait a few days before letting them back in the run?

Thank you.
