There is a thread about sprouting fodder, I think it was @gtaus . It is quite entertaining! He made a tower with dish pans and hid it in the extra bathroom from his wife. He really had it figured out!
@Sequel, Thanks for the shout out. @Ms Kurtis, I live in northern Minnesota and as such have about 6 months out of the year that we don't have any fresh greens growing outside. Last winter I grew barley fodder in our second bathroom using an inexpensive fodder tower system. The article I wrote is called My $10 Inexpensive DIY Fodder Tower with Dollar Tree Dish Bins
I also started a thread on my attempt to hide the fodder growing system in the second bathroom from my wife. Don't tell the wife, I'm growing fodder in the 2nd bathroom!
In both the article and thread, there are some great comments about growing fresh fodder greens for your birds in the winter. The fodder tower system I use takes less than 5 minutes per day and I have enough green grass fodder for at least half a dollar tree dish bin each day for my 10 chickens. It's the only greens they get for about 6 months out of the year. They seem to appreciate my effort so I am growing fodder again this winter.
Just want to add that I only propose feeding fodder as a supplement and not as a replacement for a balanced commercial feed. I keep a commercial feed hopper available to my hens 24/7, but given a choice, they prefer to eat fresh green fodder.
