My adult turkey hen is sick. She has been rather lathargic last couple days. Today she hasn't left the roost. I lifted her down to food and water, but she flew back up to bed. Face and feces were normal. I noticed when she flew back up, she left yellow secretion behind. She was wormed with ivermec pour on 2 weeks ago, as were all the other poultry. Her head is not dark, all is pink and normal colored. Hubby has been sent to feed mill for penecilian, an 18 gauge needle & proper syringe. ANY SUGGESTIONS, PLEASE?
