hurt legs

[Nanno]

I can only think that they're somehow getting their feet caught in something. Now that you've ruled out the other goat's horns, it may be time to go over your goat pen with a fine-toothed comb and see if there is any kind of wedge or hole in any feeders, fencing, gates, spools, sheds, etc. Look for bits of hair caught in things made of wood or wire. Another thought is that they've somehow bruised their hooves. If it's so bad they're laying down and putting no weight on the feet I almost suspect abscesses in the hoof. I've only seen this in horses and I've never even heard of it in goats so I doubt that's it, but right now it's the only other thing that comes to mind. Infection inside a hoof can cause swelling and inflammation above the hoof since there's nowhere for the pressure to go except up. How do their hooves look, and are they hot?
