Hi CatWhisperer, I am so sorry about your pullets and that you have this disease in your flock!

We were devastated by our diagnosis too - it’s such a game changer and really alters the chicken keeping experience!
We had intended to breed and sell chicks, and so considered whether there was an ethical way to make that work. Since the MDV virus isn’t passed into eggs, selling hatching eggs only is one idea. My DD and I also talked about having her friend hatch the eggs and sell the chicks from her chicken-free household. We did also discuss the possibility of having a “clean-room”’ for hatching, staffed by one of us that would temporarily avoid the chickens. TBH, the “clean room” idea made me nervous, as it would be so easy to breach biosecurity.... Best of luck figuring out how to go forward with your flock!
