Do you know how she injured it? Have you checked her hoof?
I also am apprehensive to call the local vet since the last time one of the goats had a swollen leg and a limp from a bee sting she told me I might need to put them down if it is broken and gets infected. Lol. My vet definitely has a way of exacerbating problems...She is still limping and lying around more than usual. She has come out to pasture for a walk with us today. She is still eating, but her leg hasn't improved yet. I saw the incident. She jumped onto an old apple tree stump that was cut down in their pen, and got her leg stuck in the crook where the trunk branched, and fell down with her leg stuck. We cut off that crook today....grrr. Her leg looks visually fine from what I can see and feel. I did think about her straining in the the hip. We think it is a strain or a sprain. Poor girl. She is such a lively girl, and it's tough to see her limping around when she is usually running hot laps with her herd mate
