Went out to water my lettuce this morning and accidentally jumped two very small fawns that the doe had stashed near some bushes. Yours is obeying instructions.....lie there and be still. My pair took off like they were fully grown. Assume the doe can pick up their scent trail. Odd that she would leave him in a driveway......few years ago, I saw one in a narrow ditch next to a road where lots of cars and people walking dogs pass close by.
