I think this whole, is Scratch Grain good or bad thing is getting as bad as the DE conversations on here.
We need to look at what a Scratch Grain is. Scratch Grain can be a single grain or a mix of grains that is meant to be pitched on the ground to encourage poultry to scratch.
Scratch grain can be a good sores of Carbohydrates, Vitamins, Minerals, Fat and Amino Acids. Carbohydrates as we know are a major source of energy so with out a good sores of Carbs. you can have lazy birds and lazy birds tend to get fat and over weigh. Amino acids play central roles both as building blocks of proteins and as intermediates in metabolism.
As far as Scratch Grain being "Candy, Crack, or having no nutrition" I see nothing feather from the truth.
There is a lot of Grain Mixes out there that make a excellent Scratch Grain with a good amount of Carbohydrates, Vitamins, Minerals, Fat and Amino Acids one of the best I have found is a All Grain Pigeon Feed in has a good assortment of grains and usually above 12% protein.
As far as how much to feed, Here is a quote from Buckeye Nutrition (Buckeye Feeds)
Quote:
Gold Standard Crumbs is a 20% protein feed
I myself feed a 28% protein Game Bird feed mixed with a 14% pigeon grain and black oil sunflower seed and my birds are doing quite well.
