Has she injured herself?

Is her hock hot to the tuch? If so its most likely a damaged joint and she needs a bit of rest.

I have her in a sling now, leg bandaged in a straighter position.. Not too tight, and medicated her with the appropriate dose of aspirin to her body weight. She seems sooooo much happier to not have any weight on the leg, and is eating and drinking like a trooper (normal for her) and will be staying indoors for a few nights. If the swelling doesn't go down in a few days then I shall take her to the vets... A chicken one 😀
