I am using pine shavings for bedding. I live in a small city, which means I have garbage pick-up and so on. Right now, while my chicks are still in the brooder, I am cleaning it every other day and putting in garbage sacks to take out front for pick-up, however, I'm not going to be able to keep that up when they are in their outdoor pen. What do you do when you clean their coop? I tried using it for mulch, but it doesn't break down too fast. How are people using it for fertilizer? Thanks for any suggestions.
