Looks like an Easter Box Turtle, next time you may want to check online to see if there might be a wild life or reptile rescue option in your area. We're lucky to have a Turtle Conservancy in the province which will do their best to repair and rehabilitate injured turtles and return them back to the location they were found in. Depending on the time of year, and extent of injuries, they will, if possible, remove the eggs from dead or dying turtles and incubate them. I was unaware of this organization for years but glad to learn of them when I did. Someone brought me a Snapping Turtle with a broken jaw (because they know I have tortoises) and I was able to transport him to the rescue centre, who were able to repair his jaw. They wintered him over (he was found in the fall) and returned him to the site that he orignally came from the following spring.
