I noticed something off about one of my hens this morning when she was super hesitant to go out of the coop. Eventually she did go out after 4 minutes of just standing there and staring, and ate and drank and did her mostly normal morning routine. One of my other hens was being super aggressive to her this morning, which is definitely not normal either. I checked her over and the only symptoms i could find are that her feet were super worn down on the bottom of her feet, that was it. I have to leave for a 2-3 day trip in 7 hours and im super nervous about this. She is 2 years old.
