??? on how long medicated feed stays in a chickens system

[tigerkitten45]

I have had my flock on medicated started now for quite some time. I know when they get to laying age that they need layer pellets. The oldest birds are ready to start laying and i did get my first egg today, so it is time to change feed, but how long does the medication take to get out of their systems?? I am also waiting on a man to come take some of my roosters so i can seperate my flock better.

I don't know how long the coccidiostat stays in their systems after you switch feeds. Most meds/wormers have a two week withdrawal time. I would wait at least that long. I would suggest looking at your feed bag and seeing if you can find withdrawal times for the specific coccidiostat used. Better to be safe than sorry?
I switched to unmedicated starter after 10 weeks......I am wondering if I switched too early?
Let us know what you find out

There really is not a good reason why you need a withdrawal time from amprollium.
