I don't yet grow my own feed, so I can't say my chickens are organic. I settle for feeding unmedicated feed, and allowing them to free-range and forage. In the summer they get a lot of garden scraps. I have a source of good quality feed, even though it isn't organic, I'm satisfied that it's decent feed.
I garden organically, have for years. The only thing I really have trouble with is the fruit trees. We goofed and got the wrong varieties for this area.
In the regular garden, I get buckets and buckets of tomatoes and peppers, squash, and so on, IF I can keep it watered. Last year we had a drought, and other factors (our previous source of water went away) that prevented us watering the garden, so we lost it all. Other years, I generally have more produce than I can process.
They're supposed to be bringing in county water before spring, so maybe, if we have another drought this year, I might be able to water enough to keep the garden alive anyway.
In organic gardening, healthy soil is everything. If you use chemicals in your garden, your soil isn't going to be all that great. Your soil will be dead, or nearly dead. Pesticides, herbicides, and chemical fertilizers kill off the beneficial microbes, enzymes, and helpful organisms, such as earthworms. Your organic plants will only be as healthy as the soil. Lots of compost helps enormously, but it takes time to build a healthy soil. It took us several years to get our garden soil into good shape. It was hard as a rock, nothing grew in it but jimson weed, thistles, and ragweed. We hauled in truckloads of horse manure and hay. We mulched. We dug. We composted. We tilled. We spent a long time reviving and repairing soil that had been killed by chemicals. After about 4 years, we started seeing results. now, several years later, we have lovely soil, most of the jimson, ragweed, and thistles are gone, and we get lots of produce, with no bug spray or weed killers at all.
You can't just plant seeds in dead soil, call it organic, and expect anything but problems. Organic gardening takes more than just not using chemicals. It takes years of bringing soil into good condition to support a garden that's productive enough to sell produce from. That's where the extra costs come in. But once you've gotten it in shape, it doesn't take all that much to maintain it. You just keep adding compost every year, and mulch a lot. Plant what is suitable for your area. Plant varieties that are naturally resistant to the local pests and diseases.
If the soil is healthy, the plants will be healthy. Healthy plants don't attract as many pests as stressed or sickly plants. Unhealthy plants produce chemicals that attract pests to eat that unhealthy plant before it reproduces.
I compost litter from the hen house, and get free rabbit poop from a guy in town, and mulch heavily. My highest garden cost is fencing to keep chickens out of it during the growing season, and the cost of seeds.
