My 2 year old male bearded dragon housed alone (no other pets in house) has never had any previous health issues. We use papertowels and butcher paper for cage floor only and any poop in his cage is always cleaned up immediately. The day and a half he has been keeping one eye, the same eyed closed most of the day. It doesn’t have any discharge or discoloration. When i first noticed it yesterday, i saw a really small piece of skin on his eyelid that i thought maybe was stuck shed. I took a damp clean wash cloth with water and was able to gentle rub it away. He still kept his eye closed after. There is no bleeding, no redness. Today he’s still keeping it closed. I dripped some clean warm water over the closed lid and covered it with a clean warm wet wash cloth for a few seconds, but he’s still keeping it closed like he’s babying it. Any suggestions as to what this might be?
