So that I can compare the nutritional values of what you get and can get against what the birds need so that you can give maybe a more balanced diet. I often go to sites like this one in my attempts to learn more. http://nutritiondata.self.com/facts/cer ... ta/10352/2
Although we mostly keep it simple and speak mostly about proteins and fat in our birds diets it is also important to look at the other values as well. Where we often eat beans or rice neither is a complete protein but beans and rice in the same dish or meal does give a complete protein. Protein are used mostly as building blocks for repairing the body, but also have other functions as well, one of these is as an energy source. Carbohydrates are the bodies main fuel source, so carbs are primarily an energy source. I think that we need to balance these in the diet as too much carbs can lead to a bird getting fat since it has more energy calories than it can use, this would mean that the bird may need less protein in its diet as more of it would be stored as fat in the liver or could be freed up for producing hormones. So what may appear to be the result of too much protein may actually be the result of too many carbs.
This is just the tip of what I am still learning and that is not even going into the balance required in the area of vitamins and minerals.
I already know that you try very hard to keep the protein level down and yet your bird and other peoples as well keep going into breeding condition out of season. Light and protein are the easiest to control but I do not believe that they are the whole story. So if I can get a list of what grains you normally buy or what is available to you I may be able to give you some suggestions. For instance you are listing both steel cut oats and oat groats in your list of grains, my understanding is that oat groats are basically the whole oat seed while steel cut oats are a rough cut oat so nutritionally speaking they would be the same So I would suggest that you use only one of them or combine them so that you only use the same amount for them together as you use for just one of them sort of instead of 1/2 cup of steel cut oats and 1/2 cup of oat groats, use 1/2 cup of them combined. And then add in a different unrelated grain.
