Hi all - being new to livestock we are wondering what we should do with the poo?

At the moment we are 'poo picking' and dumping it on the compost heap we have at our field.
Should we keep it in a separate pile or just in with gardening waste - we have a lot of gardening waste 'cos hubby is a gardener! How long will it take to rot down and what should we do with it then?
From 'p'ignorant of Norfolk!!

Thanks - Donna
