Everything was fine, I didn't notice anything different with my birds. Left at 1:30 pm today and all the chickens were happy. Came home at 7:30 pm and checked on them and one was laying next to the nest box. I slowly picked her up and she was very lethargic. I noticed another hen had some blood on her face. I then turned the pullet on her back and noticed blood everywhere! She had an enlarged vent, like the size of an egg. Looks as if the it was pecked at also. She had alot of feathers missing from that area. She was still breathing so I ran her up to the house and put her in the sink with very warm water. She could barely move except for breathing. I had my daughter keep an eye on her so she didn't drown while I ran to the computer to get help from BYC. I didn't get too far when I heard my daughter screaming! My pullet was flopping everywhere like she was having a seizure. Blood and water was everywhere. I got her out of the water and put her in the tub and she just layed there and quit breathing. I re-checked the vent area and didn't see a stuck egg? I've never seen the inside of a vent before so I don't know what I was seeing, but there was no egg. I just don't know what happened? There was no sign of being egg bound. I just feel so horrible because I didn't see any signs and now she's dead. Its just so sad. I'm waiting for my husband to come home so he can take her. I can't bare to go back in the bathroom. I'm going to do some research about this but wanted to post this first. If anybody would like I can have my hubby take some pics of it if that'll help any? I feel so bad, what an awful sight and my poor daughter...I left her in the bathroom alone and she had to see that. I never thought that would happen.
