Don't over think it. Just do it. soak the seeds for a few hours in room temp water. Rinse, drain, put them in your sprouting container, and rinse and drain several times/day. standing water is the enemy of sprouting after the initial soak. Just do a small batch at first. What have you got to loose?
Does the Scratch & Peck have cracked corn in it? If it does, I think that might encourage mold, b/c that would only soak up water but not sprout.
I usually sprout in mason jars with the commercially available sprouting lids. I just find this method to be quite easy. I'm sprouting for up to 25 birds in the winter. I like that the mason jars take up so little real estate on my kitchen counters. But last winter, I had up to 7 jars going at a time, so bought a dish pan with a dish strainer that fits inside it at the dollar store. That holds 5 jars, which can be carried from kitchen to a plant table in my living room. I picked up a multi tier sprouter at the recycle station at my town dump. I usually use that for my own sprouts.
