One of my guineas is limping -- she had been a little bit for a long time but recently it got worse and I noticed her middle toenail is way too long. I assume I should clip it. Did I mention my guineas are crazy weird ones?! I love them but they just do their own thing. I have never been able to tame them even though I held them every day as young'uns -- they just run around as a gang of 5 acting like a bunch of wild guineas. How the heck am I gonna catch her and clip her toenail? And survive myself? Last time one got badly injured I couldn't even hold her for more than a second without her going all nuts on me and scraping me up and fighting to get away. They are strong!! Advice? Also, how do I know how far to clip the nail? And what tool should I use?
