Bird seed? Why would you feed her bird seed?
It may take a week or more for her appetite to be back to normal.
I'm actually amazed no one commented on this, I'm not sure where you heard this but chins generally eat sitting up... straight up. This allows gravity to help move the food down into the stomach and is the ideal position to feed. I have also tipped chins back onto their backs to hand feed, kits often lay on their backs to eat while nursing as well.you can't lift them up to much and feed them it can go the wrong way

Right, ok that's helpful - thank you.
So she has an open wound - hence the silver (personally I still wouldn't use Flamazine but that's just me).
Septrin is not always effective - if this abscess is not responding to the Septrin then she may need Baytril - did they ever swab the wound to check which bacteria are present and which antibiotics would be effective?
It is possible that your chin has a fistula rather than just an abscess ............. I would be concerned that there is faecal matter being passed through that wound.
How often are you syringe feeding her and how much is she taking?
