Thank you for your clarification! For some reason I've not been able to find that MG/MS are reportable diseases in MI. I have been looking, but apparently in the wrong places. This is useful information that I'm grateful to have.From what I’ve gathered and read about Michigan State University on poultry diseases MG/MS ARE reportable diseases in the state as you’re putting native species in danger as well as spreading the disease to other flocks. https://www.michigan.gov/documents/mdard/Reportable_Disease_List_668347_7.pdf
I honestly dislike the ignorant people who claim that they’ve “cured” their birds of these diseases or don’t believe that they’re as serious as they are. Honestly, they are the reason these diseases continue to spread. I try to teach others the truth about MG, MS, ILTV, IC, IBV, NDV, AIV and even FC, but they never believe me and ignorantly put others birds in danger.
From my devastation and experience, if I ever have a bird express ANY sort of respiratory symptoms, it’ll unfortunately have to be culled. I’ll never buy from locals again and only stick with reputable hatcheries. I will from now on, have strict farm biosecurity and won’t allow ANYONE to just come over and visit my flocks.
It may bear clarification that I understand these are /chronic/ diseases, meaning that they are not curable even with treatment. Asymptomatic is not the same thing as cured, which is why I specifically stated asymptomatic. I'm not sure anybody anywhere on this thread claimed they had cured MG/MS. You may just be speaking from personal outside experience, but I thought that maybe needed some clarification.
I also don't allow anybody and everybody on my farm to ogle at my egg laying flock, especially nowadays when I dont even let people in my home due to COVID. I had been allowing my /nieces/ to interact with my flock, who havent been over since the summer months. Why were they allowed to interact with the flock? MG/MS hadn't crossed my mind yet, to be honest. It bears noting that their chickens came to them as rescues from an egg production facility and were already ill when they received them, which was roughly the same time that I started my flock. I'd mostly be worried about them spreading disease to my flock once it's a clean flock(if MG/MS are reportable in MI as you've helpfully pointed out, then my decision may be made for me! I intended to test already, but wasn't sure what to do once results were received). Whether or not it's a reportable disease may have no impact on their flock management decisions, and that's beyond my control so I'm not prepared to spend energy being mad about it. I'll have to figure out a way to keep kids from contaminating the clean flock while also teaching them about communicable diseases . Maybe I'll need to buy coop clothes and boots for them to wear and keep at Auntie's house. Sharing my chickens with them is part of the joy of keeping chickens.
After you cull a symptomatic bird, do you have a necropsy done? Or test the whole flock? From my understanding not all birds are symptomatic, so MG/MS absolutely can be present in a flock without symptoms. I don't believe a bird has to be symptomatic to spread the bacteria.
Or is this a hypothetical situation? If so, what would be your course of action? In my mind, if these diseases are as serious and rampant as claimed, testing one bird and getting a negative test result would not be enough to guarantee MG/MS status, and one symptomatic bird would require me to test all or a mathematically significant portion of the flock. Culling one symptomatic bird would not be enough as they could have spread it to others that are not yet symptomatic. Hopefully with your biosecurity protocol you'll never need to deal with it, but I'm interested in hearing what your plan of action is. I think the "oh sh*t" plan is probably just as important as the prevention plan.
Thanks for your input!
