Hey Guys! I was just wondering… we got an aviary about one week ago and are now starting to fix it up and put a base on it. We were going to put concrete to prevent mice but I reckon that the quail with hurt their feet and the babies could get splayed legs. (Baby quails I mean) We then started to think about sand but we weren’t sure how often to clean it, how expensive it is, if it was worth it or even if there were any easier alternatives. Thanks!
