I found a great sale on Hardwood Mulch, bought 10 bags, can i put this in the run for the chickens, I figured the mulch would keep mositure luring in bugs etc for the girls to scratch and find...I know cedar is toxic to chickens, no ingredients on the bag, i put some around some fall mums and did not smell any cedar do you think it will be ok to put in the run? Thanks for any suggestions
