My new bunny keeps itching and chewing. Is it mites or fleas?

Thanks for reaching out about Thumper and including a photo. Rabbits are meticulous groomers but mites are often microscopic. If scabs are observed, a veterinary visit is recommended for diagnostics. Good luck.

This is probably due to an allergy, although it could also be infection or mites. First of all, in order to rule out skin parasites, you will need to treat with a high quality flea treatment, then ask the vet to perform a skin scrape - this might reveal an infection or a mite infestation. If all of those came back negative, the next step is to treat the allergy symptomatically and try to discover the cause of the allergy. Three main type of allergies are usually affecting pets: food allergies, flea and parasite related ones and environmental type (allergens coming from trees, pollens, dust etc etc). Some medications can be given by the vet in order to repair any possible skin lesions (like steroids and antibiotics). Please do not hesitate to contact us again on the forum or by requesting a consultation if you have any more questions or to discuss it any further.

Binky may be suffering from mites, as may your other rabbit. Patchy fur loss with flaking along the rabbit's back is typical for the mite Cheyletiella parasitovorax, Your veterinarian may examine a sticky tape preparation or skin scraping under the microscope for the presence of mites, however, might sometimes not find any, even though they are present on the rabbit. Mites are usually eradicated easily. Classic treatment is with injectable or oral ivermectin, or a selamectin spot on given in treatments two weeks apart. As mites live in the environment of your rabbit, it is essential to thoroughly clean your rabbit's cage and disinfect areas after each treatment to control reinfestation, since fur and dander in the environment may contain mite eggs. You will need to treat all rabits in your household.

Mites would be the most common reason for scratching, mites cannot be seen with the naked eye at all (only under the microscope). you might want to take him to the vet in order to get a treatment for mites.

Jolina appears to have mange mites. This needs special medication to clear up. Either Ivermectin OR selamectin.

This is most likely Scabies (a mite infestation), this can become much more severe than that, i recommend taking him to the vet ASAP, he will need an injection of ivermectin (3 times one week apart), this should resolve the problem within 2-4 weeks.
