my chickens have been diagnosed mycoplasma (I explained the symptoms, only 1 pullet was checked by the vet 2 days after I started to treat them). I give them antibiotics. as 1 pullet got swollen face 3 days after I started the therapy, I suspect they might have caught some virus instead. they have a lot of mucus, but once the mucus has gone they breathe normally, eat and drink. would they get worse once they have started the antibiotic therapy if it was mycoplasma indeed? It has been a week since the first one got sick, still dealing with mucus but eats and drinks. thank god, all of them are still alive and I hope they will get healed. beyond antibiotics I give them acv, garlic, cayenne pepper and honey. I also put some iodine in their water (I have been advised by an old man to do so).
