There may have been a break, but it's hard to know without a vet looking at it, and having an X-ray done. If you compared the foot, to the other one, and it felt much warmer, that may suggest there is an infection at the joint. It may be worth starting her on an antibiotic for a while, and see if that helps. You can get Fish mox online or something such as Baytril. Links shown below :

In addition to the antimicrobial therapy, I would keep her in a soft padded area with feed and water provided, as you're doing. Letting her swim in the water to exercise her legs would be good, as would adding Epsom salts to the water every few days to help reduce some of the swelling, heat going on. If you arent already, I would start her on cattle B complex, which will help support overall leg bone structure, and growth. You can give her 1ml daily, over treats or orally with a syringe or eye dropper.
