You may want to be careful with the protein levels in the feed. I was feeding 24% and my turkey poult got angel wing. Not sure if it'd hurt the ducklings to give a higher protein or not. You're probably a million times more experienced than I am, just wanted to throw that out there just in case, lol.
my duck/chick starter says 20% and never had any trouble. I just love watching them! better than the discovery channel!!!
I love the sounds the turkeys make, almost like they are singing. One good reason to hatch them out! They don't do that when they grow up!!
