Yeah, it's the stupidest mission and you'll have to do it again later except in Dandelion Meadow. >_<

Anyway, first one's right beside you, second one's along the path up the hill to the Barnyard, and for the next few, go behind the place where you sleep and keep proceeding around the fences as you head towards the chicken coop and you should be able to find them all. There may be one by the mud area but I can't remember.
