Are the farmers market chick(s) the ones who are sick?13 are from Murray McMurray hatchery. 9 are from a local farmers market, but I isolated those for like 3 weeks to check for signs of any cold or mareks or cocci. They had cocci and I treated it, and they seemed to be doing better after 2 weeks so I put a few in with my 13.
