HELP! l came home today to find 2 BADLY injured hens( l BR and an araucana that is laying her clutch) ( and one hen with its head bitten off) l think a fox or a coon got in their yard. l put the 2 hurt hens in a separate cage, ( they have had the feathers torn off their backs and neck; the araucana has NO skin on her neck, just a thin flap of skin hanging. l thought she was a goner, but she laid an egg a few minutes ago! And the BR hen in the cage with her laid an egg a minute later- VERY soft shell and runny; the araucana is eating it!! What is going on? Are they laying because they are so stressed and/or dying? ls this an unusual thing? ( the last thing l expected when l went out to doctor their wounds were eggs!!)
