Just a quick update. We are in the process of installing our rain collection system, so have now expanded that system into a tilapia and duckweed growing operation to help feed us and the quail. (now I have to join backyard aquaponics forum lol)
So here's what we're doing:
1. Duckweed. We're growing it for the quail as a staple to their diet and the tilapia's diet. Right now, I have a small batch that isn't in a permanent location yet and feed about 3/4 cup of it daily between 18 quail. (We have a plan to grow it in the tilapia tank, but where it will be protected from the ravenous fishies)
2. Sprouts. I tried homemade chia pets (using chia seeds and earthen ware) but they don't seem to like the sprouts as much as alfalfa sprouts. So I am focusing more on alfalfa and wheat grass. I have a spouter in the mail, but I'm also going to try to make a big tray type that you see for forage feeders for other animals. The sprouting isn't really sustainable since I won't be producing those seeds on site, but yeah ... I was really hoping the chia would work because I could do the sprouts for that. I have kale in seed now, so maybe I'll have enough to do kale sprouts. Sprouts, like the duckweed, will go toward feeding the tilapia too.
3. Mealworms. I was trying to do the earthworm thing, but I think the most sustainable and safest thing will be my own mealworm colony raised in organic, nonGMO oats. And while that's not necessarily sustainable (buying oats), it's pretty darn close and I'm willing to make that concession. My mealworms are in the mail; can't wait to get them!
