An article in the current issue of Grit states that to get a better growth rate in dual purpose/heritage breed birds for meat, you have to feed them at least 38% protein. I've never heard that before, and it seems awfully high to me. Also hard to achieve, without getting pretty pricey on the feed. Do any of you know what the safe limits are for protein in feed, both for birds being raised for meat, and in layers/breeders? What happens with birds getting too much protein? ETA: I re-read the article, and it says 28%, not 38%. I don't know how that transmuted to 38% in my brain. The questions are still relevant, though, it's still info I need. Thanks, all!
