Hi permafolk

We're getting ready to put in our first big garlic crop at our little intentional community farm. Exciting times!

We are getting 12 tonnes of chook manure delivered this weekend. We looked for poo from an organic farm but apparently it is impossible to find and got advice from a local organic farmer that we can buy conventional chook poo and, as long as it's properly composted (to 65-70 degC) for 4 - 6 months, then the toxic chemicals inc hormones will be broken down and it is OK to help the organic garlic along.

Any advice would be much much appreciated on:
1) Where should be place this pile in our permaculture plan? Presumably it will go in our 'zone 3' paddock where we plan to do commercial growing and put the garlic crop. Not on the top of a rise? Far away from the river? All in 1 pile or spread across a few piles? Do we need to put it on a patch where we we don't plan on growing food in the future? We're in the Barringtons so get quite a high rainfall so I'm concerned about chemicals leaching out before the composting takes place
2) Any advice or links on best practice composting for such a large amount of animal poo?

Thank you so much!!!
