Thanks folks! And while the little swedies are running around my bedroom---yes, their pack n go is in my bedroom. (There was no other place to put it where I could keep out the cats. LOL)--- anyway, while they're scurrying about, I sift through the litter, which is about 3 inches of smaller pine shavings mixed with shredded paper (like confetti) from the office. Cleaning out the poo helps keep the coop like aroma to a minimum. It's working out pretty good so far. But it might be a L O N G winter, depending on how fast they grow. The plan is to keep them in the house til Spring, when I can move them out into my brand new chicken tractor---an early Christmas present from my daughter and SIL. She could never keep a Christmas secret....EVER!
