Question

Answer
I can not diagnose your rabbit without seeing it.  Your best bet is to take him or her to the veterinarian for an examination.  Skin conditions with hair loss could be due to mites, lice, infection--bacterial or ringworm, fleas, hormonal problems...  However, when a rabbit stops eating they can dehydrate VERY quickly so I would recommend trying to force feed some baby food and fluids.  Most likely s/he will need a course of antibiotics and some fluid therapy at the vet.
