What will help to keep the ammonia smell of rabbit and chicken waste from getting so overwhelming?
You can add lime. It is not good for all of your crops however. Lime “sweetens” the soil, and some crops like acid soils. I would spread the lime over the used straw, and then spread the fresh straw over the top of it. That will really help cut down the smell. You need to put fresh straw over it, because the lime would be too hard on the rabbits feet. If you could get worms to start colonizing in the litter of your critter cabin it would really help too. I live in the high desert mountain area of Idaho. We have really brutal weather here too. Snowing here today. My bunny barn can get pretty rank too. We have worm bins under the rabbit hutches but not in the winter. It gets so cold here, they would freeze solid. I use pine, and cedar shavings under the hutches to help cut down the smell. My husband is also going to cut a hole in the roof, and install one of those spinning vent things to help circulate the air (we get a lot of wind here too). I too use the same layer composting/heat meth
