My experience with meat birds:
1) They will fall asleep with their heads in the feeder if food is out 24/7.
2) Raising them on deep litter straw makes for a cleaner bird because they have a tendency to have soiled fronts because they lay down a lot.
3) They will poop more than the biggest turkey you could own.
4) Adding a flake of leafy alfalfa to the pen, a handful daily of cottonseed meal to the feeder and pigeon grit (to help digest the alfalfa) to their diet produces INCREDIBLE flavor....clean and pure even if you're feeding medicated meatbird feeds (make sure you read your feedbag labels to have the right protein amount and see what you're REALLY feeding them). Plus the added benefit of the added protein with the right Calcium

hosphorus ratio means bigger birds and diminished leg/tendon problems.
5) If you have enough of them and they all look the same, processing them is easy and guilt-free. It's not like "Yahh! Fried chicken! Hey, has anyone seen Cluckie?"
6) Carcass-wise, they are very pretty nekkid... nice and voluptuously plump. At eight weeks they will fill a gallon food storage bag nicely.
