Continuously growing wing feather

Continuously growing wing feather

Our pet Blue Fronted Amazon has a secondary covert wing feather that is growing continuously. It now extends well beyond the end of the primary feathers. See attached picture. This feather is also limp compared to a normal feather. What are the possible causes of this and will pulling the feather correct the problem? The bird is 8 years old and is one of our "own" offspring.

Our pet became sick about a year ago. He stopped vocalizing & chewing wood blocks, had panic attacks and some seizure-like episodes. Our vet was not able to determine the cause of his problems. We eventually discovered on our own that yougurt sweetened with splenda was causing his problems. The bird has fully recovered since we stopped giving him the sweetened yogurt. Milk Thistle powder was given to help detoxify his liver from the effects of splenda and his overall behavior has now returned to normal.

I'm a retired parrot breeder with many years of experience and am at loss to determine why his one wing feather is growing continuously.

How old is you bird? 8 years of age.

Did this start after the Splenda incident or has it been there longer? It started after the splenda incident during which he went through a weak moult and produced some off-colored (darker) feathers. His subsequent moult was normal except for this one feather. He has replaced his entire tail with beautiful feathers.

Pulling the feather will not help. The next one that comes in is likely going to be the same. What is his diet? Roudybush pellets with a wide variety of healthy fresh & cooked people foods. He pretty much eats anything we place in his food dish.

Has he ever been tested for PBFD? No, but our breeders were all tested (PCR) and there has been zero disease incidents with all our babies over many years. We ran a very clean MAP certified operation.

This could be a genetic problem, a follicle injury, metabolic disease, virus, nutritional, as well as toxins, or other possibilities. I'm leaning towards a pysical injury from his former panic attacks. He did hit the wall hard once.

I am not sure I would do much to treat it if it is not causing him problems. But I would have the follicle examined to see if there is something treatable. I would also test for PBFD and Polyomavirus. Thanks for your insight.
