We have young toms & hens- (Bourbon Reds), older broad brested bronzes (4H), laying hens, hens not yet laying & roosters. It is a lot easier for me if I feed everything the same feed. Can turkeys eat a higher protien (20% ) layer feed? & if so, at what age, I know that they say not to let chickens eat it before 16 weeks or so because the high calcium is hard on their kidneys, I'm assuming the same hold true for turkeys? My wife insists all the birds eat organic, & so the only thing that works right now is everyone get's the Ranchway (only organic I can get in this town) Chick Grower, & the hens get free choice oyster shell. Everbody seems to be doing well, but the problem is the organic Chick Grower is $32 a bag, & is breaking me. The Organic 20% layer is a little better, $24 a bag. Is there another choice that may not be organic but is guaranteed not to have unwanted additives in the feed? Don't want GMO corn either.
