I began reading this thread 3 weeks ago and just finished reading yesterday. I thought it was such a cool idea/ money saver that I started building after reading the first 5 pages.
I used some extra railing from my parents house(my house as well,i'm 25) and scrap plywood from my chicken coop business(www.RentACoop.com) for the main structure. The base was taken from a used bird cage. I purchased a pump, the trays the and an automated timer from amazon for around $80 total. I then bought 5 pounds each of Organic barley and wheat and it worked just like you all said it would

My organic feed is $25 a bag and I go through about 3/4 a bag a day so i'm looking for ways to save money and bring variety while also improving health(I believe it's possible)
My goal is to grow 100% of my chicken feed without growing fruits or vegetables (too much space and not enough return for the hens). I'm ok with buying the wheat, barley, BOSS and other seeds for growing fodder. Is anyone doing this or close to it? Maybe add BOSS, barley and 5 other grains to the fodder? Plus mealworms and something else and no more buying feed?
I started growing meal worms as well (more for fun but possibly to add some nutrition to their diet)
Let me know what you think.
Also visit www.RentACoop.com and let me know what you think of my business idea as well. Thanks
