I hope others will chime in, but from my past experience palpating, most of my does had babies from one end of the uterine horn to the other. So basically I felt the babies in the middle of the tummy and all the way down. It's best to wait and palpate a tad later in the pregnancy so that you are sure it's not fecals that you feel too.
I palpate at day 12-14, at day 14 they tend to be the easiest for me to feel since they are larger than the feces. I feel the babies from about mid belly all the way down to the legs. They feel bigger than a fecal pellet and they are not as hard.
