I have BBW turkeys. I originally planned on processing them at about 22 weeks, as I thought that's what I read for optimal weight. Now I am reading posts that are confusing the heck out of me. I've read that heritage breeds take twice as long, but then see a timeline for those of 22-24 weeks, which would make the timeline for BBW only 12 weeks. Then I read someone's post that said they don't go by age but by feel... I don't really want to keep feeding the turkeys any longer than I need to, but I want to get them onto corn for the three weeks or so before processing. They're 16 weeks now, what should I do?
