In one of the books I have (Chickens in your Back Yard), the author says it's important to switch to the grower feed before they are twelve weeks in order for the chicks to develop their natural immunity. I've also read (on this board) that if you've been giving your chicks medicated feed, you should keep them on it until you switch to layer feed at 18-20 weeks, skipping the grower feed. SO, I know everyone has their own theories on this but I am looking to hear some personal experiences (when you switched, why, and also, HOW--mixing in a little at a time gradually? Or all at once?) so I can make up my mind.
Thanks
