I'm in USA. I work at Petco (no, Petco did not do this). Yesterday, someone relinquished the bird to Petco. Today, the store manager took the bird to the local vet (non-avian). We are about 60 miles from the nearest avian vet. The vet told the store manager that it would take about 1 year of plucking the blood feathers. I'm hearing this third hand, so I may not have that right.
I have not held the bird, so I can't tell if tendons or bones are cut. There is no sign of blood and I think the clipping may have been done several days ago. The bird has trouble standing on the perch and seems to be off balanced. Poor thing just looks pitiful.
I do not know the age of the bird.
I thought there might be a rehabilitation process normally used for short clippings to help properly grow the feathers back out. I don't mind doing the rehab, but don't want to take on more than I can afford. Sorry I don't have more info. Just trying to get an idea of what I might be taking on.
Just to let you know -- I did take this little "guy" to an avian vet today. The physical exam showed that the bird is in pretty good health overall. There was no bone or tendon damage from the clipping and the vet thinks the feathers will grow back fine.
There still is the question of why the bird cannot stand on a perch. The xrays did not show spine or leg problems. The blood work results will be back tomorrow. The vet thinks there may have been a stroke or lead poisoning. Once she gets the lab results, we'll know more. Thanks for your kind advice.
