I read on here somewhere that you can give chicks grow feed (when they are little older) instead of the starter. I like this idea since I can give the grow feed to the hens as well with some oyster shells. Well, I went to the feed store and they have grow feed with 16% protein and 3% fat (mash) and Quick-Gro Krackettes (crumbles) with 22.5% protein and 5% fat. The mash gets wasted so much, so I bought the crumbles. Is this ok for the chicks? They are dual-purpose breeds (buckeyes, delawares, Jersey Giants, etc) - NOT cornish cross. I only bought one bag (they were gonna be out of feed) and figured I'd check on here. If it is too much fat and protein, I will mix it with regular starter to make it have better percentages. This is a different feed store than I usually go to also. I normally get the 16% protein starter. They only carry 22% protein starter. Is this ok for non-meat birds? If I mix the feed, I will get the normal 16% starter from our regular feed store. Oh!!! Our chicks are coming up on 12 weeks old.
