11 wk old chick - cant walk

[Jw_chickens]

I have an 11 wk old chick that has not been able to walk since she was about 2 wks old. She mostly sttopped growing. She's the size of a 4 wk old. She flops around her cage. The other chicks I got her with are growing fine. I'm not sure if I should euthanize her or just let her live until she dies. I put her in a cage by herself. She eats & drinks & chirps & goes potty. She doesn't sound like she's in pain. This is my first year doing chickens. We've had a few die within a few days or weeks of birth. She's the only one like this. We got 40, lost 4, then got 10 more... she's one of the last 10. Thank you for any help.

Have you tried treating her leg issue? If treated early some things, such as riboflavin deficiency can help. But if she has a slipped tendon, has splay legs, or a leg deformity, it may be too late. If you have a video that could be uploaded to YouTube with a link posted here, it might help to see what is going on. It might be easier to put her down now if she is never going to be able to get around in her flock, than let her suffer and starve to death. Chick slings can be helpful with disabled chickens to get upright in order to eat and drink. Here are some examples:

The vet gave her amoxicillin... that was it... in case of ear infection.
