Our 1 year old hen had been having watery light yellow stool a few weeks ago. Her feathers began to look less matted and we had not noticed any more. This morning, she was sitting behind the coop door by herself. We have since brought her in the house and she has been just lying in the basket for 6 hours.I forced her to drink some electrolytes water by dripping it in some bread. Do you think it could be worms?
