Limping chicken with twisted? Leg and potential SLM

[Belovedturkey]

My hen is limping and her foot looks a bit twisted so I think she landed on it wierd or twisted it. Normally I’d seperate her for a day or two in a kennel but I’m leaving until tomorrow night so I can’t do much for her until then. She is still walking around and eating, I saw her foraging so she definitely can get to the water and I haven’t seen anyone peck at her. The reason I think she has slm is because my flock just recovered from a case and a lot of people told me even if the bugs were dead their feet would look bad for a while but one of her feet is a bit swollen along with the sticking up scales but I’m worried about putting Vaseline on her when it’s getting down to 20. What can I do for her before I leave and what should I do when I come back? The one picture I got is bad but I’ll try to get a better one.
