We had a large Orpington that was running around playing yesterday and was found dead this morning in the coop. She was just sitting there still warm but dead. My husband goes out in the early mornings and said she had something clear running out her mouth. She was fine yesterday and last night so we are stunned and worried not knowing what is going on. Could anyone give any thoughts on what could have happened to her? No wounds, or evidence she was attacked or anything. Will they die from a sour crop that fast if it was that? Thanks in advance.
