What is the best kibble food for ferrets?

so far I have found two that aren’t too bad but they all seem to have a lot of junk in them; the two food that I did find are the ZuPreem Grain free and , if I remember correctly, is called Wysong 90 starch free; but I am open to suggestions if anyone knows of a better choice! I have also seen that some people recommend Blue wildness cat foods, but they contain peas! Which I heard were bad for ferrets! Also, from what I understand, they can’t digest plant based material and yet the foods that are made for them seem to be full of the very things they can’t digest; so hopefully someone can point me toward a better option, but my fur babies will definitely be getting a lot of meaty foods; I live on a farm and we raise our own animals for meat, so there is always organ meat, also should the organs be raw or cooked? I know is good from them but none has explained what the difference is?

We use SquarePet turkey and chicken.
