I asked at the feed store about some higher protein feed for turkey poults and was advised to supplement the meatbird food (21% protein) with dry COB (8-9% extra protein). I have read that scratch should not be given during hot weather. Is COB (Corn/Oats/Barley) a form of scratch? Would anyone agree with feeding it to 6-week-old poults or giving it during hot weather? Thanks...
