Anyone has experience with feeding black soldier fly to chickens

I read this article: https://hermetia.blog/blog/benefits-of-the-black-soldier-fly-for-chickens-and-birds which say all good things about feeding insects to chickens. Any experience

Sorry, but I don't consider that article to be very good.  That said, black soldier fly larvae (BSFL) are an excellent resource.  Black soldier flies will literally fly away and can't easily be used for chickens.  BSFL won't increase egg-laying quantity unless your chickens are badly malnourished.

I've been giving my girls dried BSFL as a treat for about 3 years.  They love them.  
I used to give them dried mealworms, but the BSFL has a better nutrient profile.

I'd like to grow my own BSFL to be cheaper and more sustainable, but I'm too far north to do it easily.
