David has answered David D's question with his own question. Namely, ANAEROBIC
digestion is not composting & the resulting sludge from anaerobic digestion is
not compost.
However, having digested & composted broiler house manure, the sludge byproduct
IS readily compostable though (once you acheive a proper C/N balance)...

As another David D(eCou) the simple answer to your question is yes as long
as there are not any "synthetic" materials in the litter and the anaerobic
digestion process is considered composting. Typically the litter out of
chicken houses is considered natural, although there is some concern (which
I find far fetched) about the question of the feed for the chickens being
form possible GMO sources. Since compost is normally considered to be an
aerobic process leading to stabilized humus the latter question would still
be open. It is my belief that it would still be an organic fertilizer but I
am not sure where it would fit in the current proposed regulations.
