No, it’s not bird flu. Symptoms don’t match. That was the first thing I checked.
Violence is an unhappy bird, though. She’s all miserable and lethargic and fluffed up. I looked it up and it could literally be hundreds of different things, but I started her right away on a wormer (they’re all due) and a tonic and scrambled her an egg (I know it sounds wrong, and it’s probably illegal here these days, but it’s the first thing anyone does with a Sick chook). She’s currently in Chicken Hospital (a dog crate in the corner of the room).
She’s been sick for a couple of days and I do believe she’s perking up a bit. Might be the wormer starting to work. But today she’s started flicking her head, and that’s another clue. It might be lice or mites of some kind. So when I’ve posted this, I’ll pop a sleepy chick on top of the box and have a good look with the flashlight. At her vent, which is where they congregate. Joy! And then tomorrow lucky weasel gets to soak a chicken in a bucket of warm water.
If you think it’s undignified for me, imagine how the chicken feels.
