Soaking in Epsom salt can help with inflammation so if you can soak daily that would be good just don’t let her drink the ES water since it can cause dehydration and is also a laxative
You could try something like this https://www.mypetchicken.com/products/splints-for-curled-toe-broken-legs-broken-feet-4-sizes
having support might help her walk while healing.
I'd keep up with the soaks and the other option would be a vet visit.
