G'day All, I don't think poultry manure has methanogens (Once I tried layer manure collected from the floor and it did not start, but the same happened for cattle manure with antibiotics - the dairy cattle manure did eventually start up though). I have also been told that kangaroos don't have methanogens in their gut.
I also recall a conversation about human digestive systems that indicated that some of us have "better" methanogenic populations than others (but I may be wrong here!) so a trial may be the best thing.

I have seen tanks of even 50, 000 litres (about 11,000 gallons). They can be kept above ground and you can use them as digesters. Just build a plastic greenhouse-like structure or a geodesic dome around this tank for passive solar heating. The fecal matter of all animals contains methanogenic archaea, so there won't be any need to use a culture. One time filling is O.K. I have seen that large tanks filled with cattle dung plus other digestible matter yield a steady output of biogas continuously for 6 months to a year. Ammonia should not interfere with the process of digestion. It would go out of the system along with the biogas. This is how the land fills work. Please keep us informed of the progress of your project.
