Hey y'all, Just wanted to introduce myself. I have two two-week old Indian Runner ducklings. Both ladies. I am totally smitten by them. Will take any and all advice. I did end up purchasing 25lbs of waterfowl starter feed from Mazuri. I didn't want to mis-measure brewer's yeast and ruin them forever. My girls are almost three weeks, and will be switching to grower feed. Which means, I have a ton of leftover starter feed; we've barely made a dent in it. I've bagged it up into approx. 3lb portions and am selling it on eBay. If anyone is interested, you can look at it there, or respond to this thread and we can figure it out some other way. ALSO, most important, can anyone please help me find a small batch of grower feed. I'm only looking for ten pounds maximum. Thank you so much!
