I wonder why it's "taboo" to feed a young hen around 5-6 months, not yet laying, chick starter? I also wonder why a grown hen, who has been laying, can't eat chick starter? What if that's the only thing that stopped my chickens diarrhea when I was treating them for CRD? The ones I put on chick starter got better faster than the ones who stayed on layer? I guess my question is, what is the importance of protien levels?
