I know a few people with MG positive flocks and they are not made to cull them by anyone. Keeping a closed flock is best of course but I cant see anyone "making" you do it.  They can catch it from a wild bird ! You could start all over and have it again . there are many flocks with MG .  Im just saying, Check into further before you decide.
