I've got 2 months to go before Thanksgiving, and my Bourbon Reds are getting pretty big, but a few from the last hatch are on the small side (they are 3 to 4 months old) and I'm wondering if there's anyway to focus on fattening heritage birds during the next 2 months? Mine free-range out on pasture, and they eat a good ration of corn/oats/roasted soybeans plus probiotics and minerals. I also feed them black oil sunflower seeds a few times a month. I'm going to start feeding 19% protein. Anything else I can do to get heavier, meatier birds in two months, taking into account that these are not the Broad-Breasted commercial varieties? (No offense meant here, but please only answer this if you're familiar with heritage turkeys, as "regular" turkey practices are not always relevant.) By the way, I'm assuming the toms have the capacity to get to 15 lbs and the females about 8 lbs -- I read that on here somewhere for Bourbon Reds. Thanks so much for any advice!
