Hmmm, I don't know then. Maybe he knocked himself over somehow that night and you were just lucky to find him before the morning. And you never know maybe if you didn't wake up that night in the morning he would have been back upright. And his eye, again maybe he just had something irritating it if it was only the one day. Were not watching them all the time so maybe it was just a weird thing that just happened. And ya if he is getting bigger he may be just slowing down his eating, and who only knows how long he was upside that night. And I imagine that really stressed him out so that maybe is why isn't eating now. I would just keep a really close eye on him keep offering him food and see how he does.
