Crying rabbit

Question
I have a male lion head lop-eared rabbit that is 6 years old, his eyes are watering like he u's crying altho he doesn't make a noise apart from stomping his feet.  This normally happens at night time when he is outside in his hutch locked away. He sometimes did this when he was in his indoor hutch in the winter but more so now.  He has his teeth done every 6-8 months so I know the signs to look for but I'm not sure if these new descoveries means he is unhappy or ill.  I would be very grateful for any input to help.
Many thanks

Answer
hi sheryl -make sure he's noy in a draughty place as this will cause his eyes to run and may cause conjuntivitous (cold inthe eyes) which can be cured by buying some cream from the chemist and putting on the eye.
his stomping is either boredom or he may hear something like a cat and stomps as a warning.
