Slow Cooker Chicken and Dumplings made easy

I love Chicken and Dumplings, especially on a chilly day. I'm in graduate school and it was my turn to host a study group. So I decided to whip this easy recipe up.

 Ingredients:
Four Boneless, Skinless Chicken Breast Halves
1 Can of Cream of Chicken
1 Can of Cream of Mushrooms
1/2 Tsp of Garlic Powder
1/2 Tsp of Onion Powder
Sprinkled Thyme
Sprinkled Rosemary
1 Can of Pillsbury Biscuits

Directions:
 Place chicken on bottom of crockpot
Pour in Cream of Chicken and Cream of Mushrooms
Add all the spices,
Fill till chicken is completely covered with water
Cook on high for 3.5 hours
Take chicken out, shred, and put back in the slow cooker
 Take the uncooked biscuits, and cut into smaller pieces, throw into slow cooker
Cook on high for another 1.5 hours

 My notes: This time, it came out a little watery. I do the same thing each time though, so I am not sure what was different. I am thinking of putting in more of the cream of mushrooms, or maybe more cream of chicken and then add actual mushrooms. Others also like to add veggies and/or potatoes. I'm not against it, I just never have. I am sure it's delicious. Everyone seemed to like it. :) Have any ideas for me to try next, let me know!
