Just cover the sides and top and leave him alone for a week or two then feed! He sounds stressed and just needs to settle in! Also you nee better hides than a half log. That will add to the stress! He needs a hide that has one small opening and he fits in snug. You need one on the cool side and an identical one on the warm side. Your cool side should be bumped up to 80-84! What are you measuring temps with? Where are you measuring temps? You need to have a digital therometer with a probe. The probe should be on th uth! The uth should be at 90-94! You need to measure belly temps on warm side and on the cool side with an ambient(air) temp onf at least 75! Take a pic of your setup and I can try to help make you have a happy snake!
