My poor BO Jolene died suddenly tonight. My husband just built them a new coop and she has not wanted to roost, she gets in the nest box or lays on floor and I haven't noticed where she has pooped. I got her 4 months ago and she was supposedly 2014 chick. The lady said she was broody when I got her. Her comb wasn't as bright red as my others, more pinkish really. She looked big and healthy while I had her she was just more laid back and slow, never got in a hurry. Past week or so I noticed her comb has turned a very dark red. Well today she didn't come out of coop. Her tail was pointed down and it was like she was pumping it. She also had her mouth open. Comb flopped over. She got up and came out but just stayed in the run so I checked her vent and didn't feel a bound egg. I also saw her poop a half normal half runny poop. But as the day went on she just laid around and didn't have appetite. I made a hospital cage and gave her a warm bath. I also gave her some water with Apple cider vinegar and treatment for cocci in a dropper. She started making a noise while breathing. Then she died right in front of me. She kinda did a weird jump and then slowly laid over on her back and died in like 2 minutes. I have no idea what was wrong and I'm hoping nothing contagious. Does this sound familiar at all to you?? I didn't see any mites and I didn't feel a lump at her crop either. I'm not even sure she has laid me any eggs since I got her.
