chick getting worse, amprolium not eliminating cocci

[David61]

I read where using corid/amprolium to aften will make young birds not build a natural immunity to cocci . Your one chick not immune might be getting the flock sick. cull your weak stock is an old but true practice.

was worried corid would make the chicks not immune, thanks for the advice but ill give the meds a try first since ive only culled one chicken and that one was on its death bed anyway. since i don't have a lot of chickens and these are my pets i dont think i have the guts just yet...
UPDATE: good news, the chick is now feeling better, it also stopped constantly pressing its head against its body for the first time in a month! hope the chicks will grow out without any problems and i won't have to loose any of them
