Thank you for the imput, I'll try them all & hope they help. I have 8 adult Khaki Campbells, a pair of year-old Embden geese, and these 2 Pekins who are 3 months old. They are my middle son's special request, he wanted traditional white ducks, so I got these 2 from the feed store. I sexed them myself & hope I correctly identified them as females. When they were cute little yellow fuzzies we called them The Rubber Duckies, so now their names are Latex & Vinyl. All the ducks & geese are penned/caged overnight & free-range the yard all day. These young Pekins hang out with the other web-foots, eating the stuff they find in the yard, and occasionally grabbing bites of layer feed from the dishes.
Today, after reading the prior posts on this thread, I shooed Latex & Vinyl back into their pen. Vinyl, the lame one, was still able to lead me on a merry chase across the yard. I filled a kiddy pool for them to swim in, filled a bowl with chick starter, and gave them each a few drops of non-iron Poly-Vi-Sol in their beaks. They are very content there together. I hope the rest & the vitamins will help Vinyl to heal. This evening I noticed the way she was standing, leaning far to one side in order to keep all her weight off the sore leg, poor duck.
I have a dozen or so bantams who fly over the fence into the duck pen, to lay their eggs in their houses & to gobble feed out of their dishes. That's one reason why I stopped leaving out chick starter for the young ducks, because there's no way to keep the bantams out of their dishes.
But I'm giving them starter now. If I put brewer's yeast in the feed, will it have a bad effect on the bantams?
