My guys have something respiratory, added background of known info, help please!

Hey guys, I'm new here but have read a lot and have seen very helpful people! So here it goes:

Had a previous flock with MG we culled off. Waited and started over, mainly hatchery stock and everyone is non vaccinated. Fast forward, found out we have mareks positive flock. Everyone seems well for the most part BUT now we have sow.th respiratory going on again but doesn't appear to be MG/MS. I have birds sneezing, occasionally raspy sounding and slinging snot. I have not given treatment yet because at this point I don't know what to use. They were treated for lice/mites, no recent deworming. My turkeys are randomly dying off and they free range 24/7. One d'uccle shows signs of possible coryza. No bubling eyes or snot on nostrils in anyone. Some yellowish mushy looking poop and poopy butts. Some appear to be stunted on growth. I noticed one hen, who is a faverolle, appeared to have some difficulty eating almost like the feed was getting stuck in her beak. What should I treat with? Could this be from mareks? Help!

Sorry for the circumstances. Only way to know for sure is to have a bird necropsied at your state poultry labs.

I've had necropsy done in the past, just needing to know what anyone uses for respiratory in their flock and dosage. I'm calling today to see about an RX for tylan but trying to see if anyone has the dose for la200/denegard in the water.

I understand that you have had problems in the past, but that does not guarantee that the present problems are the same. Treatment needs be specific for the disease. Good luck at resolving this. Respiratory issues can be a nightmare.

Vet suspects MG again given it seems to be in the area. Not culling a whole flock again and the one hen may have coryza. Waiting to talk to him himself to try to get the rx for tylan.
