I have chickens and over the winter I cleaned out the coop about once a week.I now have a pile which I have now layered with leaves that I also had in a pile.It is very hot,will the heat harm the worms and how soon can I use the mulch.Also I have raised beds 4 ft X 8 ft with 3 ft space between could I use chicken poo between the beds or will it still be to strong.
