Worried my Wyndotte Pullet isn’t going to make it. Please help.

[Yard Farmer]

Thank you to everyone who gave advice. Unfortunately, she passed this evening. While I I am heartbroken, I’m not surprised.
However, now I don’t know what the best course of action is to keep the rest of my flock healthy. I will be spraying them as well as deep cleaning and treating the coop with Elector PSP first thing tomorrow. Not sure if I should dose everyone with Corid to be on the safe side, or if I should be more concerned about vitamin depletion because of the mites. I know you can’t use Corid and vitamin treatments at the same time, so I’m trying to decide between the two. What would you do?

I'm sorry for your loss. She was a beautiful girl.
My apologies, I have no idea how to help.

I am so sorry to hear she passed. Please keep us posted on how your flock is doing. I would have a necropsy done. Then I would dose with the vitamins for a day or two, then start corid.
I have not dealt with the two at the same time, so I may be giving faulty advice and would appreciate it if anyone else can approve or replace that.

My thoughts are that they need to be replenished after living with Mites. I'd watch for the same symptoms on the other birds, if any appear I'd stop vitamins and start corid.
