ok i think i caught this early this is the first time ive seen him rub his eye on a branch but after i saw him do it i looked and its a little pink at the part near his nose. you can only see it when he looks backward. fixes?
Give him a warm shower ,put him on a stick then put him under the outside perimeter of the shower spray where u its not hard drops of water hold him there for about ten minutes or so..The water will flush it out hopefully good luck
