I am sorta new to this chicken thing- really new to having lots of chickens! We have only had our layers for a week today. Our coop is an 8x12 storage building- with a plywood floor. We have wheat straw on the floor and in the nests. The flies are terrible! I am going to clean it out this evening when it cools off a bit, but was wondering how often other people have to clean their coop? Does anyone use cedar chips for the floor? Does it help with flies? I know with dogs cedar is recommended because fleas and ticks don't like it.
