I have a 1 1/2 year old turkey that I noticed a week ago was looking a bit lethargic. She was opening her beak when breathing and her eyes look a bit sunken. I know that chickens can suffer from heat illnesses but we havant had any hot weather. I seperated her so I could watch her more carefully. I have her on antibiotic water now for 4 days and I see no improvment. She doesnt appear to be eating but is drinking little bits. She has runny yellow with some white poop. She is still lethargic but is standing and walking around when I come into the pen. I can't figure whats wrong with her. Any suggestions??
