Thanks for all the suggestions.
As of this morning, he is continuing to do well. He has been xrayed, etc and unbelievably doesn't seem to have any significant injuries. He has been treated with large doses of steroids and apart from being terrified, is doing well.
After a lot of phone calls, I have arranged with a friend who has a farm that we can release him on her property as soon as he is ready to be released. She has taken on a few similar cases over the years and is familar with the correct way to introduce him to his new territory.
I fully expected to have to foot the bill myself, but I am so pleased with how our vet practice has helped out, apparently they will receive £60 off the RSPCA towards their costs, but the rest is just written off. Locally they are known as being quite expensive, but if we all pay an extra £ or two on our bills and helps them tend to injured strays like this one, then I for one am not complaining.
Thanks again for your suggestions.
