I just read that you are not supposed to use medicated starter on chicks that have been vaccinated. I've fed mine purnina's med starter for 2 days and i know that they have had the cocci vaccine. I'll be picking up a non-medicated starter today to switch to. My question is: How much damage have I done? My hens are 5 weeks old and have not been on the medicated feed previously, just the last 2 days.
Thx
