The reasons for feather plucking in birds is quite long. yes, behavior can be a common reason however the other medical reasons should be explored to make sure there is not another reason for her to pluck her feathers. Definately this is something that should be investigated by an avian veterinarian. There are a number of diagnositics that should be done to see if there is a medical reason for the feather pulling and if then everything points to behavioral then they can work with you to discuss behavior modification techniques and even perhaps anxiety medication that may help. It is always important to make sure your bird is on a good quality pelleted diet supplemented with fresh veggies, whole grains, legumes, and a small amount of fruit. Always make sure there is not an environmental irritant for her such as a smoker in the house or aerosol air fresheners, etc. Making sure your bird gets enough sleep is very important also (at least 8 hours in a quite room by themselves). Providing interactive toys that are suppose to be destroyed is also helpful to keep their smart little brain occupied. Lastly, making sure adequate socialization/training/handling time happens consistently on a daily basis. Best wishing in your endeavor to help your africal grey to grow her feathers back and leave them alone.
Thank you We will take her in what kind of test should we have done? Blood work? What other questions should we ask?
