I have 6 ducks: 2 drakes and 4 hens. I've noticed that my bucket of oyster shell/grit mixture has been really getting eaten at. The chickens just pick at it but the craters left in the bucket it is clear that the ducks are really shoveling it down. Is this normal this time of year? The pen that my ducks came out of was all dirt/poo so maybe they are just eager to fill their gizzards with grit? Or are my females replacing their calcium? The woman I got them from said she gave them oyster shell but honestly I didn't see any in the pen, so I don't know. I feed a 21 percent protein feed right now because everyone is molting. Normally they get an 18 percent flock raiser.
Any input is greatly appreciated
