@ozexpat You inspired me to start putting together a spreadsheet of the nutrient content in what we feed the chickens. I've been instinctively cutting down on the feeds I consider to be high in protein, and just did a rough calculation on what we're feeding them for the first time. This is a bit difficult though, since the info available on different feeds seems to be in slightly different forms, and for some stuff I have very basic info. I'm going to add the vitamins etc. later (which will be a pain to get good data on), but I'd say the mix I just made this morning seems to be pretty well balanced proteinwise.

You're probably a bit more familiar with feedipedia than I am, don't they measure fat in any way in their tables? I still need to make time for getting more familiar with their tables.
What we're trying to accomplish with mixing the feed ourselves, is to mainly feed them domestically grown stuff. Out of the ingredients in this mix everything except for the Hold'em seed mix is grown in Finland, and the wheat, oats, peas and canola is grown about 40km from us.
The Hold'em mix is imported from Britain, so it's traveled a bit, but the birds seem to go crazy for the stuff. It has a bit of aniseed oil in it which makes the feed smell pretty nice, and I think it's giving our eggs a slight flavor addition too. The flavor isn't anise-like, it just improves and enriches the egg taste. It's made up of all kinds of goodies that would be hard to find, so I think it's nutritional value when it comes to vitamins and such is pretty ok too. Or at least that's what I tell myself.
