Anyone ever heard of this system? It is really made for cattle, horses and other large livestock but my chickens love to eat grass and other vegetation. I would like a system smaller and geared toward feeding chickens the greens they BAWK! for everytime I go outside. I also wonder if anyone knows much about hydroponics and could figure out a way to make a home based system much cheaper. These systems go for almost $3000 I did look up some you tubes on growing wheat grass and may try that it. I am only spoiling 3 full size birds and 4 bantams and think I could grow enough for a nice treat every day in the winter months.
