My DH used to live near a chicken hatchery. Every day they'd put boxes full of day-old male chicks outside the buildings for people to collect, free of charge. DH used to go pick up a box or 2 every now and then, raise the babies, keep the hens that went into the wrong box and sell the roosters cheap in the informal settlement nearby. His chickens were very popular with the locals!
I'd love to do something like that, but there are no hatcheries in this region.
I did help the battery hens a little bit though. I started farming free range chickens, selling eggs, got the locals interested and talked another farmer into joining, helped him choose chickens, gave him 1 000 egg boxes to start him off (all recycled), got him customers... he's got 200 hens now. I'm selling locally to a few households while he's supplying a shop in the next town. His wife told me recently the more eggs they sell to the shop, the more they want! They keep expanding to meet the growing demand. Bought another batch of chicks recently.
He then got another farmer into it. That guy's got about 300 hens now and is also expanding all the time. He started supplying the local shops now. (The same shop who told me their customers don't care where their eggs come from. And complained 'cause their customers are coming to me for eggs)
I also had a long chat with a local supermarket about their lack of free range eggs and they eventually got a supplier after getting tired of being harassed. They sell out all the time, in spite of their free range eggs being nearly double the price of the battery ones.
I figured if you can't beat them, join them!
