How long to feed medicated feed?

[chickylady]

Hi all. I am feeding my new chicks Purina Mills start and grow medicated feed 18% protein. On the package it says to feed until 18 weeks.
Does anyone else use this feed? and is it safe to feed the medicated starter/grower for that amount of time. I am assuming the feed company knows what they are doing.? Any advice would greatly help.

it is made for chickens till they are laying
then laying feed
medicated feed just gives them enough medication to ward off coccidiosis
can't harm them

Yes, it safe to feed them that until they go on their layer feed which will be unmedicated.
Around here seperate non-medicated grower is not available, so medicated starter/grower is what I fed until I got my first egg @ 19 weeks.
