That's because chickens raised for meat don't live long enough to be affected.
A second reason is because chickens get sick by contact with wild bids, due to free range laws for egg laying chickens.
Meat chickens don't go outside, they are kept in large barns, although without the pens and egg collection of their egg laying sisters. So they are not affected.
