Nutrina Country Feed all Flock vs Dumor All flock

[Stoney Meadow Maple]

TSC SEEMS to be carrying Dumor All Flock Pellets reliably. I am struggling to find time to get to my usual source for Nutrina, which i have been very happy with. Are they close enough to mix and match? 17%vs 18% protein which I prefer to stay under 19-20% because i have 3 Pekins who don't need extra help staying fat.
I couldn’t arrange the pictures properly but the green analysis goes with the country feeds.

You shouldn't have any trouble mixing them for your birds The DuMor feed is a little lower in calcium, so you'll want to supplement that, but you probably already are if you're feeding an All Flock.

The only trouble you might run into is that Nutrena ALWAYS has higher niacin than DuMor feeds, and they don't list that on their nutrition label. If I was guessing, I'd say that DuMor has 55 ppm, since that's what they put in all their other feeds. So while on paper that's enough for ducks, we know how pekins are. That's the amount that's in their chick feed too and that still needs to be supplemented for ducklings.

But with already adult ducks, it's less likely to be an issue.

As a final thought, you could ask your TSC if they could perhaps order in the Country Feeds All Flock for you. I'm not sure if that's one of the ones they can order, but it doesn't hurt to ask! I have them order in all my ratite maintenance feed for me.
