Will Black Soldier Fly Larva consume raw milk? What will they NOT eat?

Hello

a few days ago I got 6 chickens for free on Craigslist. I want to reduce my feed costs by feeding them BSFL. I have found some very simple designs to breed them using a 55 gallon drum and a rain gutter. I do have one question though.

Will BSFL consume Raw Milk? its Organic matter, so the I think would be yes, does anyone have any experience with that? I have been told that chicken will eat/drink raw milk.

I'm afraid that I don't know about BSFL.
But chickens LOVE milk raw or otherwise.
We also give them whey from cheese and occasionally buttermilk, if we have too much to use ourselves.

I haven't tried raw milk, my dairy in general is fine, I have done that several times. Oil from your cooking, meat - they eat most anything I have fed them.
