Hello. Not too long ago, one of my hens hurt their leg as well. We didn't exactly know how she got hurt but we knew that there was something wrong with her leg because she was limping badly. We checked the bottom of her foot and there were some some scales hanging but we were not sure if that was the case because when we pressed it she did not react AT ALL. There was no blood so we didn't keep her in. We bandaged any of what we thought could cause it which was one of her toes which had bled a bit. We made sure to check her injured leg daily and wash it with clean water. This might be very different to your hen but it will most likely be able to walk again without doing any major things. Now my hen that got injured is walking finally only limping a tiny bit when she walks
Good luck to you and you chicken
