I don't know if you have them but I have a huge mulberry tree right over my coop and area where my run will be.

Good to have you here. I'm interested in your mix. Wheat, barley and oats. What do you use? Steamed crimped oats? My chickens will not eat whole oats even when I soaked and fermented them. I wondered if you use crimped? I also bought a bag of Azomite rock dust that has 70 something...
Good for you. I wish I could do that in La but feed store is too little. I like the idea of storing in water barrels. I made the mistake of sending my SIL to the store to buy me a flat trash barrel and he came home with a cheapo one on wheels. The kind that raccoons love to open and sample.
