Can I score just the 2 sheep on those tiles with my shepherd, or do I need to add more ?
Rules for the shepherd assume to place a shepherd, draw a token and only after the next move you can score the flock (if you expand the shepherd field, of course). If you draw a wolf right after placing the shepherd, you can't score anything, even those two "neutral" sheep.
EDIT:
SBRO was a little bit faster than me
