I wouldn’t add drainage holes if you want it to stay dry, but make sure to cover it when raining/snowing, at night, etc.! Also, my run has been very muddy and I put down some mulch to help keep their feet dry-ish and it has worked great. It might be an inexpensive way to improve your run until yoNo the sandbox doesn't have drainage but I can drill some holes in the bottom, I was thinking covering it at night and during bad weather would help keep it dried out ... or should I be sure to add the drainage holes too? You've been super helpful!!
Yep! I bought a bag of sand, too, but it’s too heavy for me to pour without my husband’s help. They’ve been using it with just the pm, so I don’t think I’ll even add the sand. And I dump my fireplace ash in a pile near by compost pile & they don’t touch it, for whatever reason, so I haven’t added any to the dust bath, either. Keep it simple seems to work for me!Do you use just peat moss?
So now the tire is just a toy they climb on...
I'm thinking about suspending the feeder from the roof of the run above the tire so they can stand on the tire and eat and hopefully keep the feeder free from all the debris they kick into it.
