Im using an all living things digital thermometer and hygrometer to keep an eye on things, and his humidity is always sitting between 56-61 throughout the day everyday. (Unless in shed of course)
Post shed i Kept his humidity levels around 78-80 still to see if it would help and it hasn't done anything in terms of bringing that eye back to normal.. I even wrapped him in a wet towel but he was having none of that.. :/
Im not sure what else to do here, I'll try misting him and see
