I am looking for a local source of feed for my small flock of 16 and saw this ad on craigslist: This is a very high protein feed , great for livestock . fresh brewers grain is a mixture of spent , barley , wheat , rice and sorghum . Very high protein around 27% , this feed is clean and free of dirt or trash . $20 a sack (100 lbs) @ $20 per 100lbs $45 a barrel (300 lbs) @ 15 per 100lbs $90 1/2 ton @ $9 per 100lbs $170 1 ton @ 8.50 per 100lbs Picked up from the farm Would this be a good feed for my chickens? 27% protein is much higher than the commercial starter/grower I am giving them now, but I don't know if that's a good thing or bad thing. I would presumably need to supplement a lot of calcium once they start laying. Also what about the price? Seems affordable. My 50lb bags of starter/grower are $16/sack i think. What do you all think? This is my first time with chickens and I still have a lot to learn about nutrition, etc.
