I have 3 week old turkey babies. They are naggs..Heritage birds. The original owner was feeding them duck starter. ..I have never heard of that before is this ok.?I would of went to game bird starter. What do you think?Also how old do they stay on this feed for?And what do i switch to them next.??I was told that if the protein is to high they can get wing something...SOme thing like drupy wing. But when i do research it is telling me they need high protein. So can someone set this straight. thanks
