Milky Eyes.. o_O

OK, so one of mine is a little off colour at the moment & after an ultra sound, An X ray & some meds (the vet was so good only charged me 2p for the meds, for the xray & 1 small animal consult - on a saturday morning appointment too) everything looks normal & the vet thinks that her gut has stopped working (makes sense as they do shut theirselves down) so gave her an injection to get her going & this morning is a bit more perky.

Anyways, the hog in question is the one I thought was a she, no bald patch or anything, but I have just spotted a tiny bit of milky ness out of one of her eyes, so now I am thinking male or was I wrong to think only males did this.

If she is a he then I could have 2 males living together, or the other is a female but he does look to have rings. If I have to males then there not fighting (even sleep together) but could start so I will need to get split up I would risk 2 females but 2 males together I think is a bit no no, but then I will need to find new friends, but then if I have 2 males wouldnt they have fought by now OK I'm rambling now

Any ideas
