Fox attack - How do I look after Gertrude?

The fox got Gertrude and had carried a few yards when I disturbed him.  She was still alive but just lying on her side.  She's now in a cardboard box in the kitchen.

How long should I leave her in the box?  I want to keep checking she's alive, but presumably that would disturb her peace and quiet?  Would she be better in the hen house? Should I take her to the vet?

Thank you.  I feel so guilty, but hopefully she'll live and I can make it up to her.

Pleased to hear that she is recovering.  I would keep her indoors given the weather at the moment, unless she is doing normal chicken stuff outdoors, like preening, scratching about etc.  what about putting some poultry tonic in her water?  I use it when my hens are a bit down in the dumps, just to make sure that she's getting enough nutrients.

Mine had bite marks, but not all bled. Check them over as they might need anti-biotics from the vet if you can see holes or puncture wounds. I got 3 birds treated with enough anti-biotics for 7 days for a tenner! One bird looked mangled and the third could not stand as her wing was traumatised.  I thought it was money well spent.  Mine were attacked during the night and I kept them in their boxes overnight, away from foxy.  I took them to the vet the following day.  Two were really bad though. All survived and had long, happy lives 

I got the boxes from the place I bought them. I think they cost a quid each 

You would need antibiotics if they are bitten and have puncture wounds

One of my hens was I thought in pieces    She wasn't, it was just tonnes of feathers and part of a wing, one girls was injured by having her wing damaged and she couldn't stand up bless her.  She had the pain killing injection
The antibiotics drops are given daily for 7 days. That's a job for when they've just gone to bed. You lift them out and inject the stuff straight down their throat with a dropper. I know what you mean about trauma. They can be left to recover. If you think they need a vet don't hang about. You could ring them and see what they recommend
