Wood posts eh
Why do wood posts always have to be dead wood?
What if you planted a fast growing tree and used it for your wood post?
Go ahead and use your pine posts that won't last forever and plan that by the time it fails to grow a wood post to replace it. Fast growing hybrid male poplar might be an option.
It's a post that won't ever rot in your lifetime, provide aesthetic appearance, shade, a windbrake, compost material or fall/winter fodder for your goats and then add minerals brought up from down deep in the soil to increase top soil fertility.
A little more musing less related to the topic.
Leaves are a natural food for goats. They love them. Why not use them for hay for winter feeding of your goats? For those who are opposed tu using manure in making compost, what do you think compost is? It is something that WAS ALIVE being eaten by something that is alive, then excreted for the next living organism to do the same until the original material has been reduced to compost. The larger the initial living organism (goat, cow, sheep, chicken, turkey, horse, camel, elephant) to eat the material, the faster the breakdown to compost.
Put a notice up on the bulletin board of your local hardware stores to take other people's raked, bagged up leaves to add to your own. Then you even end up with trash bags for your non-compostable trash that would have ended up in the dump anyway.
