I would definitely consider a chick starter if I got hatchery stock, but as I have broody hens raise the chicks, and usually in spring or summer, I trust the moms to show them how to scratch and peck and find bugs and weed seeds and worms and other such delicacies, and they do pretty well.
I tried to do a little research into this, and information is not that plentiful. I did find that it has several benefits, larger crop, stronger gizzard and better gut flora. It also helps coccidia numbers in control. (Not eliminate, but allow the bird to manage it itself often times. Also keeps down the levels of campylobacter jejune in the chicken's GI track. CJ causes mild food poisoning and bad diarrhea in people, and can be spread when processing. (Similar to E Coli, but not usually with as severe effects on people.)
One other paper said that mixing 30% whole grain into a growing ration increased feed conversion by about 8%, most likely from a more active gizzard and lower pH levels in the gut.
I did look for adverse effects, and I am sure Purina or Shurgain or others of their ilk would be able to tell me how wrong I am and how their product would be so much better, but I could find no documentation or science to back this up.
So, in summary, I was able to mostly back up my preconceived prejudices (like the politicians) and will continue the feed regimen as established.
PS, Where I buy feed right now, whole corn is $10 and whole wheat is $11 for a 50 lb/22 kg bag. How does that compare to pelletized grower/layer etc? and of course, my flock get recommended dietary supplements of rotting squash, table scraps, stuff in the fridge that is growing hair, goat
