Alas! Corn and oats many years ago had much higher protein and nutrients in them than they do now.

If you have a feed mill close by ask your feed guy about products like Pro-peak or ProVAAL.(they are mostly used in dairy cattle)They will boost your protein. They are high in ammino acids.They have I believe blood meal,bone meal,feather meal ect... .Some people don't like them because they contain animal by-products which some feel shouldn't be used.The stuff I buy is ProVAAL and is 80% protein.I mix it 1 to 6 with a 16% grower mash to get my % up to around 20-23%.I think it works great for my meat birds giving them good strong legs.I've had some birds get weak legs and I've given them a higher mix and within a few days are back on their feet.
I love feeding scratch, don't get me wrong unlike many on here I see nothing wrong with it.I feel that wheat and oats are some of the best things you can feed a chicken.I don't see it as candy and it doesn't make them hot.But really it's not enough (fed alone)for a complete diet.Good luck Will
