What I'd really like to know is how many strains of Mareks is there and does the vacine just cover the "most popular" strain as does the flu vacines for us humans? I can't seem to find an answer on the Internet.
Does anyone out there know the answer to this?
I recently hatched 11 chicks that were bred here on my ranch. I thought it would be best to vacinate them for Mareks, however our local feed store chicken expert said not to worry about it because they would essentially pick up an immunity from their mama hen. Does any one else know about this...
