You have to experiment for your flock and your area. We have no idea what type of bugs live on your property. You can start a compost pile before you get your birds and get the ball rolling. Dump all vegetable matter in a pile, grass clippings, leaves..etc. In the mean time you will need to plant a foraging area for them. I plant spinach, kale, cabbage, oregano, dill, rye, rape, mustard and several varieties of greens, red and white clovers, wheat and weeds like chick weed, dandelions and thistles I let grow. Some of it grows all year round and I hand pull in deep snow some of the rye and wheat. I even cut stalks for them. In deep snow I feed about 1/2 cup of FF per bird. I do not feed and water in my coops. They need to get out even in snow and cold to eat. I will toss BOSS in the DL to help with stiring and relieve boredom. I string Brussels sprouts and make them work hard to get them too. They have a tub of dirt for dust bathing in the winter. I use a small pool.
They love most of your bugs. You might want to talk to people who live in the desert and see how they do it. You do need a ton of shade and water pools for them to lay and wade in.
