I was scratching my little green cheek conure's head and looked away for a second until he let out a little scream. I thought I hurt his eye, so I went into a brighter light to see that one side looked redder and more swollen than the other eyelid. I've been told to wait it out, but I feel like I hurt him very badly. #1 is his normal eye, #2 the swollen. Is it serious? Any advice?
