Emus here have ticks, but Greedy has a huge tick, much bigger than I’ve ever seen (say, as round as the nail on my middle finger), right up under her jaw. Moreover, she seemed oddly sluggish yesterday, and again today. She let me slide my hand right up her neck, which she has never ever done before. (Could it be something else? A small gray tumor? ‘It’ is a gray, tick-shaped thing, but the feathers of the neck obscure the spot where the tick’s head would be.)
I recall that over east there are ticks that will kill dogs.
