She was a really sweet 6 year old Buff Orpington. She was fine until a couple days ago. She hadn't laid an egg in a couple months, but my other 7 hens hadn't either, ever since the coon attack. I figured it was a combination of the attack, their age, and the shortening day. A couple days ago dark brown fluid came out of her mouth. She sounded like her lungs were congested. Her crop was flat and still was today. I had wondered if she had fluid in her abdomen, as it was a little distended. I was going to tap her abdomen tonight, to see if there was anything in there, but decided to do a bicarb flush on her this afternoon, in case she was somehow impacted......even though her crop was flat. Whenever I would handle her, fluid would come out her mouth. Her lungs sounded full too. Anyhow........I went out this afternoon to flush her. I flushed once (with a baby's syringe) and a bit of old food came out. I flushed her again, and her comb turned dark and she couldn't breath. She died. I drained her abdomen and got clear reddish fluid out. That made me feel a little better.........that it was a more serious illness and I just didn't kill her with something little and reversable. I know she was sick. But I feel so awful that I pulled her out of her crate, told her I was going to help her feel better, and then killed her. I hope I didn't put the 2nd flush into her lungs. I couldn't even try to hold her upside down, as that made her worse. I just feel so awful. I should have just left her alone. I fear she thought I was hurting her at the end. I don't want to feel this bad.
