I hadn't had any hints that she was unwell but I had noticed that she was fluffed up a lot since the weather turned cold in the last week or two - but without displaying any of the usual signs of listlessness, off food, not making any sound etc. She was still eating (very well!) and displaying her normal happy chicken type behaviour. She was 4 years 2 months old and a red hybrid like the one in my avatar.
The other 2 old birds aren't showing any signs like that though, and the one who died had gone through a full moult recently so she had a nice new set of feathers.
Not looking for sympathy (but darn it, why is it always your favourite that goes?
