Hi! I will be getting two female ducklings May 2nd. I have been getting mixed information on which feed ducklings need and for which weeks. I am mostly hearing this: 0-3 weeks 20 % chick starter/grower 3 weeks -laying maintenance laying- layer, obviously is this accurate? I also wasn't sure what the "maintenance" feed means? Is that like a grower/finisher? And also does anyone recommend any specific brands for the babies? My adult ducks are fed DuMour which is the big yellow bag sold at Tractor Supply.. One last question.. I have a laying female who is on laying crumble, but for my 8 mont old drake what should he be eating? I have him on a 15% grower/finisher.. Is this right? Once again Im not sure what a maintenance feed is, is this one? Please help! Thank you!! -Carly P.s. I will be adding brewers yeast for the ducklings for niacin, for any one concerned!
