I'm pretty much the same as madamwlf, for what it's worth 

 24% chick starter up to 6-7 weeks, then 20% "fnisher" or broiler crumbles for everybody. My grown-up girls free range (not sure how this is gonna play out when I have multiple pens...) and everybody gets ground-up veggies just about every day. (So far -- I'll be out by January 
 ) I throw a handful of sunflower heads in the stalls every couple of days (grow 'em, snip the heads off, let 'em dry -- the chickens pick out the seeds just fine 
) and some scratch now and then just for fun!
 
Okay, am I the only person here who runs all her leftover produce thru a food processor for her birds? My chickens LOVE beets, so long as they're chopped up into bite-sized bits. And cabbage. And turnips!
