We found our 3 year old Americana hen this morning at 10am in the coop lying on her side with a crooked neck and her beak in the dirt. She has been vomiting a brownish yellow liquid and sometimes clear drops come from her beak. Her legs are limp and straight back. She has trouble holding her head up, but it is better than before. She was fine first thing in the morning. She is bothered by moving and has been sleeping. She does not want food or water. She has not pooped in 5 hours. Could this be a scorpion sting? Has anyone else had this happen and how did you treat it? She is in the house now in a dark, cooler room.
