Sprouting is easy and the birds love the sprouts. I buy organic seed mixes from Sproutpeople.org online, and usually get a couple of pounds at a time. Mine like the li'l bird mix. Basically, you soak for 8-12 hours, then rinse it well, drain the water, and then you rinse it well and drain every 8-12 hours. I do mine for two days. The sprouts come with instructions and they also sell easy sprout sprouters which makes it really easy. At the end of the sprouting time, when the sprouts are almost dry, I empty them into a baggie and refrigerate. I usually give them a teaspoon or two each day and they really love them. I have never had a bad batch, never had any mold or mildew grow, and it sprouts every time, plus they are organic. Here is the link: http://sproutpeople.org You can learn all about sprouting and how good it is for your birds on their website. They also do a kit for a beginner, that has the sprouter, seeds, instructions, etc..
Personally, I bought an easy sprouter and used that. It worked wonders. I just used the seed mix I was buying for the birds (I got mine from a feed store by the pound) and gave it to them every day in the morning. It can spoil so be careful of that.
