I just noticed that one of my hens has very long nails. They are in fact so long they are starting to curl a bit and turn to the side. The other hens all look okay but I am worried this is a potential injury or, at the least, uncomfortable. She seems fine and is getting around just fine. Should I do anything? Do they need to be clipped? If so, what is the best way to do it? Is there a way to prevent this: perhaps she needs access to a harder surface? The run she is in has soft ground but there is also a wooden ladder to the coop, a wooden awning that they spend a lot of time on and a big log that they sometimes stand on.... Any advice is appreciated! Thanks so much!
