I found a local mill that supplies area farms with "Broiler Mash" I didn't recognize the name of the company but the farms are small local market types. 50lbs for $13.00 good price for this area. So I know nothing about mash. He had a sample in a baggie. It looked like powder. Do I feed the "mash" up to slaughter? I don't have to wet the mash all the time? Do I? Right now I feed my layers crumbles. They will stop eating when the feeder has to much powder in it. Will the meaties eat powder? Any thoughts or opinions would be welcome.
