Fodder is a fancy way of saying food for livestock. Since we are in the middle of winter and there is no grass growing, we are growing some fodder inside our house. Strangely, hubby thinks this is a fun hobby. He has some shelving set up with a few containers. He starts by putting grain, like wheat or barley, in a bucket of water for 24 hours. Then he transfers the grain to plastic bins and waters it daily. The grains sprout in just a few days time and are ready to deliver to the animals within a week.
Our current system is very small. We may expand it in the future, but for now it is enough to give all the animals a small treat every day or two. Fodder=animal food. You are welcome.
