What if I were to treat everything exactly as I would if I had her put down, had a necropsy done, and it came back Mareks? Scrubbed everything down, sanitized the heck out of everything, vaccinated every new chick that hatched, used the extra vaccine to inject all the other birds just in case it might help for prevention if they haven't been exposed, even though they are older (what could it hurt?) . . . but just kept her as a pet. I would keep her quarantined from everyone else. It wouldn't be easy. I would have to scrub up between contact with her and other birds, change my clothes, everything. But if I was willing to do it -- could it work?
The question is, would you really be comfortable selling birds that might be carriers or even sick that looked healthy ?? As a buyer I would not be comfortable buying birds from you, Not trying to be harsh here, but I would be devestated if I were to buy your birds and wind up having to lose my flock to something like this. I know its hard to put a animal down but really the test results will solve alot of your delima at least if you know the truth, you could tell perspective buyer the truth. It could be something else but your really not going to know the truth and be able to be honest with the customers without doing it, Please do the right thing, I know you want to but its hard losing something that means so much to you. I Wish you the best, Sandy
