New Babies

If you are getting an error where there is only an 'attack' option and no 'pick' option on them, you've already 'picked' that one. You have to move to a different area and 'pick' unique ones, you can't wait on respawns.

Just Southeast of the quest giver is a field of these little guys following their moms in a train. You can grab one per "train". I found most of mine here. There are also individual ones sitting around water pools west of Stonecrag Gorge, as another user pointed out.

I found a lot of these, enough to do the quest twice over, over by Oshu'gun and the water around it.
