Sick chicken,

[dcullon]

When I went to check for eggs today their was blood all over the inside of one nest. I found the chicken it was acting sick and had blood all over it. I picked it up and looked close thought maybe it's wattles were injured from a fight or something. She started girgling blood out her mouth. I think she was injured inside or something. I ended up having to put her down
Does anyone have any ideas?
