I have 17 chickens that are 12 weeks old and 11 that are 8.5 weeks old. I have been taking a couple scoops of scratch and spreading it in their run about twice a week. I have starter in a feeder for them free choice 24/7 so is the scratch ok? I do it because there is not alot fo grass left in the run and they need to scratch and peck. I have not seen much of a reduction in the amount of starter they are eating because of this. Just wondered. I guess I could just spread feed like I have the scratch instead if it aint good for them.
