Last week I found one of my Araucana hens dead with part of her rear eaten. (I'm thinking the other chickens pecked at her after she died.) Her death was sudden and unexpected. Tonight one of my sons went down with his camera and noticed that three of our Araucanas have bloody spots and missing feathers in the exact location of our deceased hen (except hers was much worse, down to the bone). Do you think the other hens are roughing them up? We have 10 hens, no roosters. We raised them from peeps and bought them at the same time. They are about 8 months old. We have one Arauncan that is fine, which surprises me because she is at the bottom of the pecking order. We have four Araucanas, two Amber links, and four Reds. Could it be lice and they are trying to scratch themselves? I have no clue what is going on. Please help.
