On Thursday last, I grew concerned about her medicines. She'd been taking the same antibiotic at low doses for something like five weeks at that point, and the angry red remained. It seemed nothing could get rid of it. My sister, who studied to be a physician's assistant, said low-dose antibiotics for a long stretch of time was the best way to breed resistant strains of bacteria in a wound, and that worried me.
So I switched her from Baytril, which was the antibiotic the avian vet said was best suited for reducing the inflammation of her preen gland, to Amtyl, an antibiotic I had on hand after some respiratory problems in the aviary last year. It's near the expiration date but not quite there, and it seemed worth a shot. I also added the Metacam anti-inflammatory to her water for three days.
It's now day four, and it seems the switch was a good move. She's put on weight, she's eating well (especially when I put millet sprays in her cage), and she's starting to act more like a parakeet and less like a patient. Her feathers are growing back from where she'd been plucking, and that vague baldness around her eyes is going away. She's brighter, sitting up straighter, and becoming more vocal.
I've quit washing the injury, leaving it alone to heal. It does get checked daily, and the e-collar occasionally needs reinforcing since she's still chewing it at whenever her beak can reach. Even athletic tape, supposedly the strongest out there, slowly peels off the X-ray film and gauze padding, leaving streamers that collect seed husks and have to be trimmed. After a while it looks like a flower, opening around her cute little face, and then the danger becomes the tape sticking to her feathers, or her getting a good grab at it and wriggling the e-collar off. Yep, she can do it.
