BlaBauve- I totally understand where you're coming from and the decision you're trying to make. Exactly!
I think it's a personal decision about how to deal with it. Some people would automatically cull-- never, ever treat anything respiratory.
Some people 'live with it' and deal with it...and may (or may not) cull birds that don't recover well on their own, etc.
recentner is right--- it's estimated that upwards of 90% of backyard flocks are MG positive. I've spoken with some USDA poultry "specialists" (vets) about it (county extension gave me a toll free number for the state I'm in) and it's an overwhelming problem/disease. (as are some others) A great number of the sampled flocks in their testing, that were positive, were completely healthy...owners had no clue...and had no idea when or how the birds were infected. It's said if you take live birds on and off your property, you'll most likely encounter MG, or other things-- additionally. The safest way to build a 'clean flock' is from tested/certified clean HATCHING eggs.... buying day old chicks from certified clean stock would be your next safest. (but many of the most popular hatcheries do NOT test for MG in their breeder flocks) Then-- you must practice very good bio-security. This includes and all in-all out policy with a 'rest period' between flocks for things in the environment to die off. You must take care not to 'track it home'... from poultry shows, swap meets (just don't go to those!) and even the feed store-- technically, if you were at the feed store with someone else that was "dropping" the virus from their shoes/clothing after caring for their flock...and you tracked it straight home and used the same shoes/clothing to carry the feed to the birds-- that could track it in and infect them. Maybe that's not the easiest mode of transfer-- maybe that's a lower risk of contamination, but it IS still a risk.
THEN, we have WILD BIRDS. Wild birds can be carriers... drop poop among your birds environment...and your now clean flock is sick...again.
(one of the preventative ways for bio-security of MG and other illnesses in commercial poultry businesses is entirely enclosed housing, where no wildlife/birds can cross contaminate) Most people with backyard flocks don't wish to keep their birds confined and enclosed 24/7 like the commercial poultry industry does.
That said, to be a responsible BREEDER, or to sell hatching eggs, you should make every attempt to have a disease free flock. I'd still lay odds that fewer of them are totally free from any carrier diseases, they're just not known about.
I won't let a live bird leave my property for any reason. Well, maybe to a vet if needed...but you know what I mean. I won't sell birds and potentially infect someone's clean flock. I don't have any interest in selling hatching eggs. I don't show and don't ever plan to... it's just not my cup of tea. Basically, my birds are for our egg eating and entertainment purposes. (pets) Let's face it, mostly entertainment purposes--- it'd be FAR cheaper to just BUY eggs, even from someone else with a backyard flock.
SO, after digesting all the statistics, and the likelihood of STILL not ultimately ending up with a 'clean flock' if I culled every last one of them... I decided to NOT cull just for the sake of starting over. But, like I said, I won't treat sickly birds that can't handle it again and again. But if they can "recover", live and act healthy...lay eggs and make us laugh... great, they can stay! I think SO many backyard birds ARE carriers... and no one is the wiser.
I don't have any problems with eating the eggs after any medication withdrawal period. I mean, *I* have taken antibiotics many times over the course of my life and don't think I'm forever tainted. Granted, no one is eating me... lol... but I'm sure the doses of meds I consumed while sick (and needed them) were in concentrations thousands of times higher than I'd ingest even if I ate the eggs WHILE the birds were ON antibiotics....
And... commercial poultry feed has meds mixed in them 24/7 to "manage" and reduce loss in their flocks. Even eggs and birds going straight to human consumption. Trust me when I say that just about ANY backyard flock, no matter what they're fed or medicated with...is healthier than the vast majority of commercial birds. (I actually owned (co-owned/marriage) a poultry farm 20+ years ago...with 160K layers... then we converted to broilers for several years. Having a backyard flock is different...but you still get your eyes REALLY opened in those businesses.)
ANYWAY-- I'm really not trying to sway you one way or another, just telling you to do your research! How heartbreaking would it be to cull your flock...then find yourself in the same situation with another flock? Given the prevalence, that was the decision maker for me, I guess.
