Slipped tendon? Graphic pic, i guess

[cottontail farm]

I put down this pullet today. About 8 weeks old she hatched fine but her leg started turning at about 3 weeks. She ended up hopping with one leg nearly backwards, weight on the back of her foot. Never appeared to be in pain from it. Is this a slipped tendon or?

Wow, that's super weird. I have no idea how that would happen. Hopefully someone else will know...

That sounds like a twisted tiba leg bone deformity. Did you take a picture of her standing or walking before you put her down? Unfortunately leg bone deformities and slipped tendons account for a lot of chickens needing to be put down. Sorry for your loss. Here is some reading and pics about leg bone deformities and slipped tendons:
