After doing some research this morning, I've come to realize that it seems MOST small flocks have at least one bird that is a carrier of CRD/MG. If that's the case, how do you know that you're not going to end up with it in your flock when you buy hatching eggs from someone? I even read a post where a BYC'er had to eradicate her entire flock after the state vet confirmed the presence of MG in one hen (the state didn't mandate it, she just chose to do it), and eggs that she had shipped had to be destroyed. With that being said, is it even safe to buy hatching eggs, since the disease can be passed from hen to egg? I'm not trying to stir up an old can of worms here; I'm genuinely concerned and wonder if maybe I've gotten in over my head by having backyard chickens...
