Definitely lots of bedding, as they got older i had to put new bedding in 2x a day, they poop ALOT... 20lbs of feed seems pretty high.. I keep track of every bag of feed that I buy and mine only went through 500lbs of feed for 35 birds, which averages out to be around 15lbs of feed per bird. I fed my birds 24/7 and once i put them outside i put their feeders away from the coop, so they didn't sit and eat all night. I have heard pros and cons of both 24/7 feeding and 12 on and 12 off and honestly I think that when you take the food away for 12hours these little guys are starving by the time you bring their food and will just gorge themselves (jmo)...
