Sounds like a good setup. Some foods are more like candy (tasty, high calories, but little nutrition) and may need external moderation. I believe most other things that are higher in important nutrients, but not exceptionally tasty, will be more likely to be eaten as their bodies require it.
And yes
@Chickeeaholic, I'll keep people posted on how I'm progressing with duckweed. I did my research about a year ago, but as I recall no one used it for more than 10% of their overall feed. I have no idea how they mixed their feeds, so that's why I started with direct feeding. I'm sure not everything in commercial pellet feed would be desired by chickens if offered straight up, but are only included to balance nutrients.
I was interested in duckweed because when you try to feed your chickens outside of commercial feed, protein (and in particular Lysine and Methionine amino acids) is harder to come by and duckweed, azolla, mealworms and black soldier fly larva were some of the easier sources that you could produce at home.
I'll go back out and re-search for some of those research links and drop them in this thread for anyone interested.
