The gaps in the fence are too small for chickens to squeeze through bit the fox manages somehow.
No need to be rude anyone.
I'm glad I asked for advice anyway.
Thanks

Welcome anytime for advice. I am sure no one mean't to be rude at all, they just want the best for you and your livestock Hope all goes well and that you can get rid of the fox once and for all.
All the best

I agree that a terrier is not what you need.  Fencing is the answer I suspect.

Sorry, I'm blunt - the welfare of the dog is an issue here in my view.  It is paramount! For that reason my Brittanys are kept separate from my birds, (purely because they'd constantly be picking them up and bringing them to me!  ; and my birds are kept safe from any foxes with high, non climb fencing on three sides.  They are free range in daytime, and the dogs are outside next to them (fourth side) but no access, they have kennels, and beds to go in if it's wet.  At dusk the birds come inside, and soon after that I shut their pop holes - and if the ducks don't come in when they are told, I set Allez on them!    They come in pretty quick when they see him coming!
