Hi Flyladyrocks. Re: the chipped trees: If you're using it in the run, I'd dump it in an out of the way spot, let it age for a bit and then throw it in the run. If it's in the run, a bit of cedar shouldn't be problematic. (Just my opinion) If your run is huge, you could just dump it in a corner of the run. Generally, when worms have moved into a pile, it's in perfect shape for the girls.
Re: DL in the coop: Is there a reason why you want to rake it every day? I generally let the girls take care of it. They are so busy mining for creepy crawlies that there is never any visible poop or odor. And if I feel that they have been too busy outside to tend to the DL, I just throw a bit of scratch around, and they get back to work.
Thank you for your dedication to the VBS program at your church. So many children benefit, and so few people step up to the plate to make the program work.
