This is very unfortunate but I culled my last flock because they were showing symptoms of respiratory disease including, eye bubbling, rattled breathing, nasal discharge and sneezing. I never got them tested and I assumed it was MG so I culled my entire flock. I sanitized and built new pens and waited 6 months before getting any more chickens. All of my new flock are from NPIP certified breeders. Just had a cockerel having rattled breathing and culled immediately, now another rooster is having nasal discharge and eye bubbles. I’m thinking it’s MG once again, I have no idea how they became infected. I take all proper bio security measures, my pens are also bird proof and I don’t let anyone onto my property if they have chickens and are not NPIP certified. I’ve done everything I can think of to keep my chickens protected but it seems that it’s impossible. I wanted to raise and sell chicks and hatching eggs but that plan has been crushed once again. I’ve spent over $1000 on these chickens, some rare breeds and all bred to the SOP. I was planning to get NPIP certified soon. What is the least expensive way to get one tested to confirm that this is MG? If they are positive for MG is my only option to cull all of them? Could I sell them for meat? Is it possible that it isn’t MG and it’s something less concerning?
