It is Dumour Starter and Grower. I think I'll take the un opened bag back and get a different brand. I've been checking the "Raising baby chicks" thread, and seeing that a lot of people have been having issues with their chicks demonstrating this condition. So much for just giving birds the packaged food "because it is nutritionally balanced and gives them every thing they need." Even the stuff I bought says it is good for 0 - POL. I think the issue is Vitamin E deficiency, but it stands to reason that if that is deficient, other nutrients would be lacking as well. In the mean time, my chicks are getting vitamins, spinnach, eggs, grit, and a variety of grains in addition to the chick starter. Since I've been supplementing, their crops are much fuller, and they seem more active.What kind of feed was this? I never really studied the label, but I usually use Purina "start and grow" (at least I think that's what it is called). I've never had an issue with it in the past. I'll have to check the protein content on the label....
