Hello!! I was wondering what people are putting in their run? Currently, I have just the dirt that was under the run at the beginning. I'm still new to all of this...my 8 babies are only 3 mos old. (It's getting hard to tell them apart as they're growing to all look the same! * I thought of using those colored circles for their feet) Anyway, I have seen posts that people use sand, some use hay, some hate hay, some use grass clippings, etc. I'd love to know what exactly to use, or if it's fine to keep it the way it is. Treats - what do you give, and do you give them every day? Thank you!!
