Thank you all so much for your responses, and for welcoming me to the site. I've been visiting the site and taking away advice for a while but it's taken my little trauma today to actually post something!
All the girls are fine thanks, think I'm more traumatized! Although they had only this week found the house end of the garden, and I've had a lovely week sat working on my laptop in the kitchen watching them all day, they have now retreated back to the other side of the house where I can't see them. I'm hoping they will be brave and come back to the french doors so I can enjoy them all again.
I have a strange shaped garden (imagine a zigzag!) and I am now seriously thinking of getting a large run built. My daughter uses a strip of land at the side of the house that is covered in recycled tyre bits (she has a slide etc on there cause if she falls off we are hoping she will bounce!) and they like kicking about on it and seem to find plenty of things to have a peck at and eat so I think my daughter will have forgo it for the girls (yet to tell the Husband as it will the most expensive chicken run base ever known!).
Hopefully we will never see a fox, live on a small new build development and have never, ever known foxes in the area, fingers crossed.
Am off to town tomorrow to buy a very large water gun!
