How to sprout seeds
You will need: a jar or plastic cup-like container, paper towels or calico, rubber bands, a bowl, a sieve. Possibly apple cider vinegar.
Soak the birdseed in the jar/cup for 1-8 hours in water. Put it in the sieve and wash it under running water. Rinse the seed properly, and let it drain. Put the seed back into the jar/cup, cover it with a paper towel and secure it with an elastic band. Gently tip the jar/cup so that it is on an angle with the jar/cup opening facing downwards and use a bowl to lean it into.
Every 12 hours, rinse the seed thoroughly. After 2-3 days you can start feeding this to your birds. Do not keep sprouts for more than 1 week, and continue to wash and drain them regularly. I use a cap or two of apple cider vinegar diluted with lots of water, and soak them for a minute or two before rising the sprouts well, as a way to inhibit bacteria. I will eventually post a how-to film on youtube to show how to do it step by step.
