A blood feather is a new feather growing in on a bird. The shaft of the feather is filled with blood, until the entire feather is mature. Problems can occur if the bird breaks the blood feather, causing external bleeding from the shaft. In this situation, it is a good idea to contact your veterinarian to see if the feather needs to be removed from the bird. My pet was diagnosed with mites.
Mites are external parasites that can be easily treated with the right care.
Most mites are species specific and will not transfer to you, or to other pets in your household. I have an animal and am thinking of getting a companion for them. Most importantly, your new animal should receive a physical examination and lab work as soon as possible. This is to ensure that you are bringing home a healthy companion for your already healthy pet. The new animal should be kept quarantined until all lab work is completed, and any treatments carried out if needed.
