I've noticed over the past few days that one of my hens (Adele) had bloody spots on her comb. This morning I confirmed that she is being bullied. One of the other hens flew at her and full on attacked her! It was brutal! I am still in shock to see such a mean display. Poor Adele, she seemed so scared!! This kind of attack happened two more times while I was outside with them over the course of about 5 minutes. One time a couple other hens joined in too. I know it happens, but my hens have previously been pretty good to each other. I suspect that it started this week because I haven't been letting them out as early as usual due to being sick. If I start letting them out at their normal time will this stop the issue or do I need to do something more drastic? Thanks in advance for the help!
