Thank you so much for your words of kindness and I am so glad you find this thread helpful...I was hoping it would be such. I hope you participate here as much as possible.
1. Ashes that get wet may have caustic runoff from the rain..not sure about that. All the soils and grasses around our ash piles don't seem to be affected at all. But the point is, they run off and are absorbed into the soils. They do not hold the water and/or the resulting caustic lye in a dried form. Our ash pile gets wet, it gets dry, it gets used and the cycle happens every time it rains.
If it was caustic to the chicken's skin they would not willingly bathe in it, believe me. They pretty much know what to eat, where to dust, and what to do to stay healthy if left alone.
2. I don't see why not. Be the first to try it and let us know how it comes out. Some are fermenting alfalfa meal and cubes on the FF thread and are quite pleased with the results.
I'm thinking of wood ash in a half wine-barrel (rethinking that...since barrels need to stay wet to keep from falling apart) and some soil/sand/wood ash in a protected area...although not rain-proof. I would like a rain-proof overhead off the large coop. DH refuses to teach me to use the wood saw. Will have my brother teach me instead. I work at a 40 acre farm and we live on a 5 acre farm. DH likes to fish (from Sept. thru Mar.) so the 'honey do' list is over for this year.
We throw ashes around acidic plants/trees near the house to nuturealize the soil (blueberries, pine trees, oaks) that we want to add some plants around the following year. Mainly drought resistant medicinal herbs. DH insists on having a lawn around the house. Not a fan of lawns that needs watering....but fine with me as long as weeds/herbs are allowed to sprout and grow and no spraying. Our teenagers are let out from their run to explore. I do this before DH gets home and then give them their sprouts to get them back to their run before DH gets home. Works like a charm Shhhhhhhh
