Hi All,
I have been doing what I think is deep litter for two seasons, but am experiencing a hang up with ammonia buildup during the winter and spring thaws. Also, I am not sure if I should be aiming for a dry, dessicating situation or a moist composting one. I have cold winters here, with the last two having an extended period of hard freezing, with nights in the twenties to ten below temperatures. My normal maintenance is to toss up new material under the roost as needed to cover droppings. During the summer this all stays really dry, smell and mostly fly free, but after the winter long freeze, everything melts at once and there is suddenly a lot of wet ammonia build up. So far I have removed and replaced all the bedding immediately when this has happened, but wondering how others manage in cold winter climates?
I am using a thick layer of either hay or straw as bedding. Maybe I just need to add much more bedding more frequently? I have a trailer coop with a floor that would rot, really like the idea of composting in place, but not sure if I could do that in this sitation. Also, I am not sure how that can happen though during the coldest months, even with some water added?
(Also, if this has been already answered in the bowels of this extensive thread, please let me know!)
Going in another direction here, one thing I tried this winter which might be a good combination in general is the addition of charcoal to the bedding. A new/old idea in the organic grdening world is what they are calling biochar. Basically it is charcoal that is infused with plant nutrients, added by mixing it with compost or in this case chicken droppings. It holds nutrients, so is a long term fertilizer in the garden. I make mine by doing a fast burn of my seasonal prunings in a shallow pit, then water quenching the bed of coals before it has a chance to burn down to ash. As charcoal also picks up odors, it seems like a lot of the ammonia could be captured and used in this way in addition to what it is getting from the solids. I had one thaw this winter with no odor, but the second one generated too much for the capacity of the amount of charcoal I had, so might not be a real solution for me and the amount of ammonia that is generated from a winter's worth of frozen poo. Really looking forward to using it on the garden though.
