If you are thinking of getting some chickens for their eggs, I suggest 8 ad a sweetspot number. naddr1qqxnzdejxsergdpexgmrzv3sqgs8ksa3ewj00rvwdp9grgx0tlx5laq7pvryzxaggrt8tj4mncx5tgcrqsqqqa28epaq93
"They say" if every third home had a few chickens, factory farms would be gone tomorrow. A little idealistic, but you get the idea.
Modern intensive animal farming is such a fiat construct. Ignore the billions of hectares of land that could flourish if animals were around fertilsing and disturbing the soil. Instead get in as many tractors as you can outside, while cramming as many animals into an interior space as possible, be that a cage, a pen or soft-focus barn.
But keeping such a density of life healthy is no easy task. It creates problems that need solutions that generate economic activity that ushers in other problems.
Just think how many vets are prescribing all sorts of products that keep hens from keeling over, but the medications stay in the animal and pass through to the animals that consume it, mainly homo sapiens.
Or behind the scenes, you may not be aware of the literal shit show going on to store, and dispose of effluent. The expense, the processes, the nonsense to keep it out of the water supply, often unsuccessfully. Madness.
And consider the side effects on human health as we are drilled to eat three square meals a day (or in Spain, eat something 5 times a day!) On top of that constant food craving, we are sold ever less nutrient dense comestible "stuff" to sate those cravings. It seems we don't eat to feel literally full, we eat until we have enough micronutrients to meet our body's needs. So we have to eat so much more than our ancestors to find those nutrients, and so we get obese, and so it goes on.
This circle can only be broken by backyard chickens. I'm kidding, but you get the idea. Start somewhere.
