I can't decide what to use in the outdoor covered run for my ladies. I've heard good things about both. I know my girls like to search and scratch around in our wood chips/landscaping mulch when they are roaming but will that be too much moisture in the run for them. I don't want to grow any nasty stuff in there but I want easy. I like the idea of sand and how it may look but is it really easy? I'm not sure I want to rake the sand everyday and certainly not more than once a day. Do the girls get bored scratching around in sand and not finding anything? We would still have some sand for dusting/bathing purposes. We will have a large run, I don't want to make a costly mistake. My husband says wood chips, a very good friend says wood chips. I'm feeling the pressure here. Please tell me what you prefer and why. Thanks in advance!
