Okay so I got back today (I spend the weekends at home in the big bad city). Straight after work I went out armed with vegetable oil (rapeseed) and the vaseline. Washed her foot in warm water, then dunked it in the oil and then slathered on vaseline for good measure. I'm not taking any chances! Sick Chicken wasn't thrilled. Here she is inspecting my handiwork:
I think her foot looks a lot better since the last time. I hope I'm right and that it's not just wishful thinking and the fact that her foot is now clean making me think that. I vaseline'd her other leg too just in case. Haven't been able to catch the healthy chicken (Dinosaur Chicken) because she makes velociraptor noises and scoots away the minute she sees me stretching out my arms.
Here's Sick Chicken's oiled and vaseline'd foot on the right:
I need to get a soft brush - some of the deformed parts look like they're at least a bit separate from the leg itself. Will it just fall off itself eventually do you think? Do I really need to try cutting it off? I'm afraid I'll hurt her!
Funnily, when I started taking photos, Dinosaur Chicken stalked over very interested and tried to peck the lens out of my camera. The other day when I was washing Sick Chicken's leg she started pecking at the soap! She'll peck at anything!
Dinosaur Chicken, starry-eyed over my flash:
Thanks guys for all your advice. Going to oil up the roost tonight. Sick Chicken sleeps on the floor because of her fungusfoot but hopefully soon she'll be mite-free and able to roost with the Dinosaur!
Oh also, slightly OT but Dinosaur Chicken very rarely lays and when she does, the eggs have hardly any shell. Does anybody know why this would be?
