Chickens getting sick in my flock seems to be spreading!

[laws24]

Help! I am new to chickens I had a few older hens and added a straight run this spring from a hatchery once we realized 12 was too many roosters I have been selling them and traded a few for baby pullets about a month and a half ago.
Fast forward to this week, I have been having chickens start to get "colds" coughing, runny noses, one with foamy eyes,some not eating at first then seem to recover and return to normal behavior, others have no normal behavior at all.
I'm very concerned something has bad has been caught in my flock and I am understandably concerned that I need to do something about it. Can anyone help! I have looked up everything and nothing seems to quite fit but would love some experienced answers! Thanks in advance

Could it be Infectious coryza?

Your birds probably have MG or Coryza. You can also find more information in the section link below.

When bringing in new chickens to your flock you must isolate them for at least a month to watch for symptoms of disease so that you won't spread something harmful. A good source for looking up symptoms to get an idea of what you might have is: amerpoultryassn.com/respiratory_disease.htm. Many diseases are chronic which they can get again and infect every other bird you bring home.

It sounds more like MG to me when I look at the APA is there a high mortality rate? Does it affect ducks at all? How important is seperating now that I have enough infected say 4-5 in a 30 chicken flock? I dont have the best situation to seperate them. But I will if I have to

also where do you get Tylosin?

tylon is at tractor supply stores in my area, you want the tylon 50 mg

From what i have heard, ducks do not get MG (although i have no experience with ducks).

You can treat they symptoms of MG, but they will always carry the disease and will spread it to any new birds you introduce.
Also, you can never sell, show, or give away any birds with MG. Birds with MG will have a lower hatch rate and they can live with it for years.

You can treat your birds with Tylan. 1/2 cc per grown bird per day for 3-4 days. 1/4 cc for juvenile birds. Given oral is better according to my reading.

I got this info from reading and have no experience with MG. If my birds did get MG, I would cull them all.
Someone with more experience may have better information.

my friend is going through MG and has lost most of her birds to this. Hope you dont have MG, but it sounds like it good luck.

Is getting rid of them better than treating and keeping them? I haven't seen any head flipping or anything affecting their air sacs, does this mean it could be something else? possibly just a cold or upper respiratory?
