Some girls just have a hard time. I have a 7 year old who's beak I have to trim. She's much older then your lady though.Yeah I just went snd checked the others and everyone else’s nails look short like the photo you shared. Of course, they’re all different breeds, but that’s interesting hers are so long! The enclosed run has lots of levels and ladders. The enclosed run is 12x12 and she’s one of the more active birds. Always jumping up the various roosts and platforms. Maybe she injured it.
She laid an egg the day I found her, but hasn’t laid since. I assumed she was too stressed
For eggs, you also mentioned that she has been in the dark. Less then 8 hours of sunlight a day will cause hens to stop laying.
