Sneezing chickens

[Wyorp Rock]

I culled the hens that were were still showing sighns my question is the young pullets i have in another barn when there ready to lay and i move them to this place were the sick chickens were will they all get the sickness and not lay well or will they be fine?

And should i just cull the remainder 3 or see if they pull through there still laying fine

There's no way to know if the pullets will become ill when you move them.
To help reduce chances, you could sanitize the coop with Virkon.

As for culling the remaining 3, that would be a personal choice, if they were sick or exposed, then likely they carriers of whatever illness you have been dealing with. Getting some testing to find out more would be one way to go, then you have a better idea of what you need to do.

Check with your state lab about how to submit samples or you can use an independent lab.
