Unwell or just knackered?

One of our Rhode Star hens isn't her normal self. I let the others out into the garden but she stayed put and I had to pick her up and put her with the others. As they pecked around on the grass she didn't seem that bothered. I noticed that her tail is down a little and the feathers around her bum are moving in and out occasionally, like she is clenching but other than that there doesn't seem to be much wrong - eyes are clear but she seems to be blinking a lot more than the others, nose is clear, no signs of injury, being picked on or pests. Crop is squishy, doesn't feel full whereas the others are relatively hard. She goes to the food but has a peck and then walks away. They are all approximately 26 weeks old.

Either her or the other Rhode Star laid a very large double yolk egg today - could she just be knackered from that? Sadly we can't tell which one laid it but they have all laid today. I didn't notice any problems over the weekend and was out today so didn't see her during the day.  Any ideas?

Had you checked her vent for a prolapse ? It'll be puckered and sicking out a bit.
 
Also check her crop first thing in the morning before she gets to any food. It should be empty. If it's still bloated, it could be sour crop which will require treatment, possibly anti-fungal from a vet.

Checked her vent tonight, all looks ok. It took a while as I haven't had to look at it before and there were lots of feathers in the way.

She seems to be back to normal although only one of them laid today - perhaps some sort of industrial action? I hadn't been notified of any ballot and, as one of them laid, presumably she is a "scab?"

I bet the management are laying to break the strike 

Sounds like she was just a bit under the weather. They do that sometimes for various unknown reasons.
