I have been reading an awful lot on CRD (I probably have three pullets with it now). It seems that if you want to enjoy raising chickens, you are bound to experience this disease at some point in time. I just do not see how it is avoidable. It spreads via clothing, air, the ground, wild birds carry it, etc.... Unless your backyard is in a bubble I think you will get it. Am I missing something here? Many folks are culling when they see a wet nose or hear a cough because they are scared about CRD. I am new to this hobby and I know there is a lot I do not know, but am I way off here?
