I've got a four week old chick that has Perosis, or a slipped tendon in one leg. At two weeks, I noticed she was holding her leg out at a 90 degree angle from where it should be. I didn't know why, and by the time I found a remedy to fix it, it was too late. She now holds her leg out so that her foot is facing a complete 180 from where it should be. She's eating and drinking well, and doesn't seem to have any swelling or pain, but moving around is a chore for her. Will she have any quality of life, or will she just suffer? I've never had to cull a chick before, and though I've already researched culling methods and have decided I will use the motor oil method that essentially makes them fall asleep and never wake up again, I would prefer to not have to cull. I was hoping her condition wouldn't get worse, but unfortunately it has, and I'm unsure if it's reached the point where not culling her would be cruel.
