Bulk seed

[GetFitWithKrista]

We are looking into mixing our own feed using this fella’s formula on a YouTube video:

Premium whole oats 30lb

Whole corn 20lbs.

Black oil sunflower seeds 20lb

Split Peas 10lbs

Flax seed 5lbs

Add DE as well maybe a cup?

So we see that TS is where we can source the first three ingredients, but I’m wondering gbwhere Incan buy bulk split peas and bulk flax seeds.
Does anyone else mix their own feed, if so what fro you use, what amounts and where do you find your ingredients? Appreciate any help.

I know this is an older feed but I watched this same video for the DIY chicken feed. He made a second video after this saying why he no longer uses this recipe and he purchases regular premixed food. Here is the video if you're interested:

Kind of annoying - he should really take down the first video.

Can you give an update? Have you been making your own food? How is it going?
