I understand now. A word about Marek's. If you even so much as suspect that dead hen had Marek's, it would be best to cull this rooster instead of giving him away. Marek's is passed to other chickens as easily as breathing. Once in a flock, you can't get rid of it. Even if you culled every chicken in a Marek's flock, the virus can live months and sometimes years in the soil.
