Thanks Chiqita.
As I have stated before, the Mg that I might have is so mild that I am not even sure we actually have it. My birds are completely asymptomatic and have been the whole time. The two that tested positive for it were in my quarantine pen.(thank goodness I quarantined all birds coming in!!!) But because I might have it, I have decided to close my flock to any birds going out so that if I have it I am not spreading it. I have brought in birds several times and none of them have ever developed any symptoms. So that leads some people to think that my flock doesn't have it. But I still wont take the chance and my flock is still closed as far as I am concerned to birds going out.
Maybe someday I will do blood tests on them but so far haven't done so and not sure what it would prove since blood tests only show active cases, I would still not feel comfortable opening up my flock even if they all tested negative.
It limits me and I have to be very choosy about what I bring in because I cant just get rid of the extras and as a result I have a much higher ratio of roosters to hens then is optimal, (about 2:1) But because I freerange on several acres with an electric net fence the girls can pretty much get away and most are not overmated. I only have one missing a few feathers and it could be because this is moulting season. and I have given several Roosters to a coworker to eat after explaining the Mg situation to him.
Some breeders are actually thrilled to sell to me because they know I will never be competition to them. Some not so much because they are afraid of it. But there are far worse diseases out there to be afraid of than one that doesn't affect the chickens unless you stress them by putting them in tiny horrible cages and treat them like crap. like Mareks or Coyoza.
is that a more thorough explanation?
