Questions sometimes arise as to how much this or that turkey should weigh. Next season I intend to keep weekly weights and make some growth curves. Just for fun, I weighed some of my birds at 20 weeks. Here is what I found. St Bronze tom 20 lb St Bronze hen 11 lb Bourbon Red tom 15 lb Bourbon Red hen 8 lb Narragansett tom 15 lb Narragansett tom 11 lb Narragansett hen 6 lb (this one seems a little small, even the midget white hen is bigger then she is) Royal Palm tom 13 lb Royal Palm tom 11 lb Does anybody else weigh birds as they grow?
