I've been using the fresh eggs daily brewers yeast blend for 5 months and mix it daily with their feed. It always seemed to go to the bottom of their dish but they seemed to clean it up pretty good. Since then I've got the probiotic, kelp blend and flax as well. I do the same, mix it daily and even if most of it is at the top when I give it to them, it looks like a good majority of it is left at the bottom when they're done and they don't clean it up. I'm wondering if they don't like the flavor? It's got good reviews. I'm wondering if anyone might have suggestions as to how I can give it to them and have most of it get eaten? I have 10 ducks so it's quite a lot to go to waste when they're not eating it all and it can't be saved for the next day because it's damp.
