I have a small flock of 11 birds. (hens and 2 roos) They are around 16-17 weeks old now. They are just about out of "Chick Starter and Grower" feed, I am gonna stop by the feed store today to pick them up some more. I usually buy 50 lbs. at a time. My question is should I get them "Layer" feed, or is it too early. I could get a smaller bag of the starter/grower feed but just figured I would just go ahead and start them on the layer feed. Is there a danger in starting them too early on the layer? Why are you not sopposed to give them layer feed when they are little anyways? And what about the roos? Should they be fed something different? Sorry if I sound stupid or if these are stupid questions.
