Ultra Blend Ferret Diet.
I can't find any reviews for this, does anyone have a review for this? 

Here are the first 6 ingredients (makes up a majority of the food)

Three of them are grains. Ideally, you want at least 4 of the first 6 ingredients to be meat based. Since ferrets are obligate carnivores they get all necessary nutrition from meat. They can't digest grains. 

Feeding grain-heavy foods makes them smellier, they poop more, and can contribute to insulinoma.

IMVHO there are MUCH better foods out there.

I'd consult this food chart for more comparisons. Ideal foods are in the green sections.

Thanks!
The Ultra Blend stuff is what their previous owners have been feeding them their whole life so I just kept buying that, I am trying to switch them to a raw diet but I realized that I don't even know how good the kibble I am feeding them is, until I can transition them into it, I want them to be eating something that has lots of protein 

This is a good ferret food chart list, there are others in the stickie post called "food charts" at the top of the Food Posts.
