Hello hello,
I have an ISA Brown hen, she is about 4 1/2 years old, the oldest of my flock of 11 hens (and one rooster) and also The Boss of the flock. She's always been very healthy (apart from a very soft egg shell that got stuck in her vent many years ago, we managed to get it out). She had a few lice last month, but we treated this and they're gone now. She's never been broody and is usually the first one if there's food. We call her Hendini as she's an escape artist too.
The last 2 days she is constantly talking and fluffing her feathers. She's not broody because she is walking around like normal on our croft. She still lays an egg occasionally.
I checked her over very thoroughly yesterday and today and I could not find anything wrong with her, she's a picture of health!
Why on earth is she talking all day and fluffing her feathers?!
