Thanks.
She was very emaciated for a fair while, she would only eat tiny amounts of every food I offered. I figured it was most likely internal parasites so I bought some medication and got the QT ready. Before treating her though I decided to try feeding her some fresh garlic soaked food, and to my suprise it worked. Within 10 days she had become an absolute pig, developed a round tummy and finally began to fill out around the head. She's not out of the woods yet, young angels can be tricky to keep alive even when healthy but she's looking good for now.
Selcon is something you soak food in right? I don't think its sold in Aus but we have a few similar products, might try one and see if it works.
