Just came across an injured adder in the road, about 18", it's midsection is immobile but head and tail still moving. No signs of punctured skin. Do you think it has any chance of survival? I've emailed the nearest snake people but I wondered if there's something I should be doing while waiting for a response. I'm worried something is going to make an easy snack of it, we could put it in a box in the greenhouse for example, should it be offered food? Any advice would be appreciated, cheers
