How can I check for fleas/ticks/whatever else in my partly white bunnys fur?
Regular grooming is essential for bunnies; when brushing him, check his fur very carefully, and see if you find anything along the lines of such pests. I do know one thing, if the insides of his ears are red and crusty, then it’s definitely a case of ear mites. But again, give him a good brushing, exam his coat very carefully while you brush to see if you find anything along the lines of mites, fleas, ticks, etc; I’m sure if that’s the case, a bunny specialist can provide you with essential removal care (I say “specialist”, because most vets only treat dogs and cats, you have to find a vet that has doctors that specialize in small and “exotic” animals to see your bunny).
