Hi Folks! Just wanted to relate what I finally settled on for litter in my brooder box last August, after experimenting with several options. What worked really well for me was to use potting soil -- the particles were too small to be a danger to the chicks, it stirred up easily and kept the odors at a minimum, and I could toss it all in the compost bin or garden when the chicks were finally in their coop! Anyone else have success with this as litter (or problems)?
