A few days ago a hawk got into my coop and killed one of my blind hen. My other three hens where cowering behind their waterer, and they were terrified. I'm not sure if this stressful event has anything to do with my hen acting odd but thought I should include it just in case. I noticed one of my hens acting slightly odd. Her comb has turned a dark red/purple color and she seems like she is in pain. She is hunched over with her rear end closer to the ground than normal and she is rather tired. I have seen her eat and drink however she seems to not weigh as much as she used to. I went to check on her tonight and she seemed to not be doing so great. Someone please help!
