Pearl has a sore.

Scaly face? I don't know what it looks like on a tiel. But when I saw it in Bonnie I just knew. at first I thought the same (an injury) but then I saw more and more feather loss so I just knew

Perhaps you should order some ivermectin. Lisa said it worked quickly on Bonnie. If you order it now, you can watch the spot for a couple of days while it is shipping.
You could also call and ask the breeder.

You might want to look at the history of Lisamarie's posts when her budgie had scaly face. If you click on her name, you can go to a list of her recent threads.

It is not unlike a boil that has drained and is on the mend. It is dry and less red than yesterday. However the area around does look rough, or dare I say scaly. It is not worse. Maybe better. I need a friend to come help me examine her. She is not being very cooperative. I see zero change in her behavior. In fact yesterday I saw her play with a toy for the first time.

Thank you for the link Lisamarie. I am going to go ahead and order it. I can't get a good picture. Pearl isn't being cooperative and I live alone, I will ask a friend over to help. I tried to separate sweetie today just in case it is mites and she isn't infected yet. Now I know how Diana felt. Sweetie was in her old cage in my bedroom. I purchased another calcium and mineral thing and was putting it in her cage when she escaped. Usually she wants me but today she flew straight back to her new cage and Pearl. She hadn't eaten anything all day. Once in her cage her and Pearl both started eating up a storm. I don't have the heart to separate them again unless I absolutely have to.

Thanks Sarah. I hope whatever is going on in your world keeping you from the forum isn't serious but rather just the cycles and busyness of life.

I have been watching Pearl like a hawk and I am determining that she has some type of feather mite because the same thing is now happening on the other side of her face. I know so many of us purchase the mite meds online and have successfully ridden our birds of mites. I have chosen to take Pearl to the vet and I will share why, it may help others make their decisions when and if this situation arises.
Through research there are many different types of mites. One medicine may kill multiple types of mites but not all. I am uncomfortable administering what is essentially poisen unnecessarily or in Improper doses to my fragile feathered friends. I determined a treatment via the internet for Pearl that required two types of meds purchased from two suppliers and with the cost of postage if I take her to the vet it would only cost me $15 more with much more assurance that the correct meds and dosages were being administered. Of course the vet could be more $'s if they order additional test, but if that is necessary it could be my internet diagnoses and treatment plan may not have corrected the problem anyway, which then would cost more $'s and more worry regarding the birds health. I want this resolved sooner rather than later. I like the two birds I have. If my treatment hurt or killed them I could get another bird but I couldn't get another sweetie or Pearl. Because I do have a little in the bank I am able to dip into my ever decreasing savings and take Pearl to the vet. I figure chances are good that if I purchased the one med on line it would correct the problem, but... If not, as a new inexperienced bird owner I want the assurance a vet will give.
As a aside note, those thinking call the breeder. I did, she may have a couple breeding pairs and successfully raised some clutches (is that what they are called?) but she is inexperienced with health or mite issues. She has been very lucky. Also she is dealing with a family emergency this week. Pearl and one other bird were purchased from another breeder and my guess at this point is Pearl and the other bird brought mites with them from the other breeder and the lady I got Pearl from should probably treat her four birds as well. But I of course I will wait and hear what the vet says. I did read a bird can have mites from the nest and they can remain dormant for .... Not sure if they can stay dormant for 3 years, which is how old Pearl is.

I am sure you are doing the best thing. When is the appointment?
