The title says it all......we had to put 1 down this morning, she had bright (neon green) poops yesterday but acting normal. This morning she was hunched over in the corner and when I picked her up her right side of her face was swollen and bloody, eye was slightly bulging and her neck was completely turned 180 degrees. A very sad sight to look at. I had DH shoot her. I have multi age chickens in 1 coop. My larger birds all free range but the 10 younger (age 8-12 weeks) do not leave the coop. I had 1 hen with wheezing problems and gave her Tylan 50 injectable and she recovered nicely. Now I see lots of diarrhea but no blood. 1 chick with a watery droopy eye but again no other symptoms. Could this be fowl cholera? If so how do I treat?
