Drooling lethargic chickens since introducing new ones

[RaisingBabies]

We have 2 americauna and 1 rhode island red chickens. About a week ago we got some orpingtons from a poultry farm.. One was gurgling and drooling but we're still newbies and don't know everything about chickens, so we didn't think anything of the possibility that it could be sick. All our our hens have stopped laying eggs, we thought it was because we changed their food. We noticed more and more of our flock is getting sick (we have 6 chickens total in the coop). Now today they are all sick and standing/laying in one spot, when usually they are all active Also they are all drooling and gurgling and lethargic.. And I haven't seen them eat or drink. I'm not sure what to do, but I read something and it sounds like the respiratory disease. They are in really bad condition and we are scared and need help. Thanks for any input

Do they have white bubbles coming out of their eyes and nose along with a swollen face?
