Hi - I have a raised house (about 2 feet off the ground) with an attached run. I am confused - does a deep litter method need to be on the ground to work properly? I mean - if you have a raised house with a raised wood floor - does a deep litter method really work - or do you just have a pile of pine shavings in there that needs cleaning out? I can think of problems with wet/decompsoing pine shavings (or whatever) on wood... Trying to figure out what's best for the (hopefully) girls that will go in there, and what's easiest for me at the same time! Thanks.
