From the pictures you posted the other day she doesn't not have a broken leg.Afraid video is out of the question as I don't have any idea how to work with UTube other than to watch stuff.
Merek's Disease has crossed my mind as Tractor Supply chicks aren't vaccinated for anything which I think is wrong.
Broken leg has also crossed my mind which is why I believe the best thing is to take her to the vet.
No, she can get to food and water just fine, she is in the house today and I'm not going to disturb her.
