I bought off of meyer this year and they will be 8 weeks on monday. I am going to have to keep them at least another week as they are only 3-4 lbs live weight. I started them on starter for the first few weeks and then switched to grower. they are also getting grass, squash and apples plus the have feed 24/7. They did feather out better than McMurry's do. With the cost of feed I have $6.00 each into them right now.....They will be $8.00-10.00 birds by the time they reach 8 lbs.
