Hi, I’m a new chicken owner and have been researching the best options for feeding. I’ve read to give them whey for methonine (sp?) and/or egg whites. What type of whey is used? The powder form? Is so, how much? And should the egg whites be cooked or raw? I also read to give turmeric and cayenne. Are these in powder form found in the spice aisle or fresh? And how much is considered a serving?
