..my coop is 8x8...the run is 8x16(that they have access to during the day..plus some yard time)I use pine shavings in the coop....i have been emptying out about half at a time when cleaning..about every few weeks..the litter is pretty thick...maybe 6in high...i dont want to change the litter to little and they get sick or something...but..i hear alot of people mentioing the deep litter method..(only my floor is vinyl..not dirt, so i'm not sure that the DLM will work for me?)..any ideas that you guys do is much appreciated..thanks..Wendy
