I lost a hen last week, no idea why, she just suddenly went downhill over a few hours and died, and she wasn't one of my oldies. Yesterday I had to put one of the older girls to bed as she just stood in the garden, and today she's just standing around looking very old and tired. I brought her in and gave her a warm bath, which she loved. She had a very yellow mess at her rear end, and I wondered if she had a broken egg inside but couldn't feel anything, she hasn't laid for about a year. She's eaten some food and been drinking water but I don't think she'll go on for much longer. Both her sisters died last year, she's 6 years old now so I suppose it's to be expected.
