Hi snufflewoofs
Sounds as it you are well placed if any hedgehogs have health problems, with your experiences with your Mum rescuing hogs.
Re. Linking with other gardens – they don’t have to be interested in hogs, just to not mind if they go into their gardens – and why would anyone mind – but then I am probably biased!
Re. the hedgehog crossing sign. I contacted our local council a while ago. As you suggested, it was apparently the parish council who had to ask for and pay for any sign. The obstacles, otherwise, were that it would need to only be a temporary sign (they seem to be more concerned these days, than they used to be, about excessive ‘street furniture’) and also suitable siting (bearing in mind it being a temporary sign). There didn’t seem to be any problem about getting a sign made – as long as someone else was paying for it! It seems that hoglet time – so round about now – seems to be a peak danger time, with another one when the clocks change in the autumn, so it may help, even if it had to only be temporary.
