Oh and I forgot to say in my previous post, the nutritional profile of soaked seeds/sprouted seeds/sprouts are all going to be different. Seeds are packed with energy and vitamins , but they are not that easy to digest. As they start to sprout, plant enzymes break down the seed, making it easier to eat and releasing important nutrients.
Generally speaking, sprouted grains will have more Vitamin C, Iron and folate and the plant protein will be more easily digested. As the plant continues to grow, it will start to use up the stored nutrients to help the plant grow and develop so sprouts tend to be less densely packed with nutrients, compared with sprouted seeds. They are lower calorie and similar to feeding fresh veggies or salad mix. Still good, just in a different way.
Ideally, you want to aim for soaking over night, then sprouting for a day or two (maybe longer for some seeds or large beans). This should give you the best "bang for your buck". However, there is nothing wrong with feeding a little earlier or later. They are still good for your bird.
Experiment to see what works best for you.
