Eggshell, Bone + Vinegar = Hens Laying, Sows in Heat

How do eggshells and bone become calcium a plant or animal can use fast, and what does Cho do with them and with egg yolk oil on the farm?

Friday afternoon, after the hands-on making outside: the tape opens on Drake's porch interview, then a short clip of the interpreter, Kim Chang, cooking egg yolk oil at a camp stove. From 5:01 Cho teaches at the front with two big jars on the table: eggshells in vinegar (Reproduction, WCA) and charred cow bone in vinegar (Structure, WCP). He holds up the eggshell jar at about 17:00 to show the shells rising, and the bone jar at about 25:30. A flip chart with Korean notes stands behind him but isn't readable, and there are no slides or handout here.

• Egg yolk oil (outdoor demo) — From the interpreter at the stove: start with one dozen eggs, go to two dozen once you're good at it; she does 36 eggs at a time at home. Cook until the eggs look done enough to eat, put them in a bowl, run an immersion blender over them, then put everything back in the pan 'to make it really fine' and keep cooking. About an hour; longer in wind. The tape never says whether only the yolks were used.
• Reproduction (WCA), eggshell in vinegar — Cho: eggshells in vinegar. Eggshell is alkaline, vinegar is acid; they react, and the calcium in the shell dissolves into water-soluble calcium. Shown in the jar. No ratio or timing given on this tape.
• Structure (WCP), cow bone in vinegar — Cho: cow bone holds protein, starch/carbohydrate and fat, which can't react with vinegar, so burn the bone first. What's left is calcium (phosphate), which is alkaline; in vinegar it dissolves. Shown in the jar. No ratio or timing given on this tape; his recipe book gives charred bone : BRV = 1:10, about 7 days.
• Hens that stopped laying after a molt — Cho: 'that's when you give this'; the interpreter says WCA and WCP together. No amount; Cho says he'll explain feed-making later.
• Sows that won't conceive or come into heat — Cho: mix WCA and WCP and shake them into the drinking water; add Medicine (OHN) with it so the effect comes fast. No dilution given on tape. His recipe book gives WCP at 1/500 in drinking water for pregnant or ovulating livestock.

1. Start egg yolk oil with one dozen eggs; a batch takes about an hour

   Interpreter at the outdoor demo: one dozen to start, two dozen when you're good at it, 36 at a time at home. Cook until done enough to eat, blend with an immersion blender, back into the pan. Longer in wind.

2. Egg yolk oil on a livestock wound heals it quickly

   Animals that fight and get hurt: put egg yolk oil on the wound.

   ▶ 5:16 As spoken

3. Give it to crops and lots of flower buds set

   'I'm not a doctor... but from my experience growing crops.' Cho says 'this'; the interpreter says 'these two' (WCA and WCP). No rate or timing given.

   ▶ 14:22 As spoken

4. A hen 'has a period every day'; a molt is like one that comes all at once, and she stops laying

   When all her feathers fall out she stops laying. That's when you give it: hens that had stopped start again, and the laying period gets longer. No amount; feed-making comes later.

5. Eggshells rise and fall in vinegar because alkali meets acid

   Cho holds up the WCA jar. Eggshell is alkaline, vinegar is acid; they react and the shell's calcium dissolves into water-soluble calcium.

6. Press egg yolk oil with a loving heart; after a fight with your spouse the oil won't come out

   'These things aren't dead. They're all alive.' Not in words like ours, but living cells talk to each other.

   ▶ 24:18 As spoken

7. Burn the bone first: protein, carbohydrate and fat block the vinegar

   Cow bone is living bone. Burning removes protein, carbohydrate and fat; what's left is calcium, which is alkaline. Vinegar (acid) then dissolves it into water-soluble calcium (phosphate).

8. Sows that won't conceive or come into heat: WCA + WCP shaken into their drinking water

   Cho says they come into heat (발정). No dilution given.

   ▶ 27:56 As spoken

9. Add Medicine (OHN) with WCA and WCP and the effect comes very fast

   They're nutrition that has to get into the blood, so circulation has to be good for them to be absorbed.
