Mine (18 hens and a roo, approx 17 weeks old) get constant access to a feeder filled with organic grower crumbles, which I've now mixed 50/50 with organic layer pellets (ever the optimist, lol, can't wait for that first egg!) to get them used to it (they seem to really love the pellets and my cross beak has put on weight since I added pellets - I think they're easier for her to manipulate and swallow).
They have a huge 2500 sq ft run filled with plants and grass and bugs where they forage from sun up to sun down (the run is made of electric poultry netting with fishing line criss crossed over the top to keep out the hawks). We also give them treats every day. Usually clovers, lawn clippings, spent veggie plants, kitchen scraps and sometimes we'll buy a box of blueberries or a big watermelon as an extra special treat

Our compost bin is also within their run, so they spend lots of time in there, helping themselves to all sorts of stuff.
When we don't have any fresh treats for them, they get scratch and black oil sunflower seeds. We even keep several logs and flat rounds (sliced tree trunks that we saved when our lot was cleared) out in the run so that every couple of days we can roll/flip them and let them get all the worms and bugs that have gathered underneath!
On weekends, when we're around to sit outside with them, we let them have full free range all over the property (5 acres of woods, but they stay in the yard, within 200' of the house) for a few hours at a time. They typically head back to their run with crops bulging, lol.
Happy, spoiled chickens
