Trying to figure things out...

So, I've got two litters right now.  One born from Hope X Chester.  She had 4, 2 bucks, 2 does. One of each is blue Vienna Marked.  There is something wrong with the little VM buck.  His head is tilted to one side.  These kits seem to have finer fur, thinner faces, longer thinner ears. The bodies seem narrower, but have a nice topline. The other litter, Georgia X Heart, 2 BEW. They have nice solid bodies, very round, with round heads and nice ears. They're eyes are smaller than the other litter.  

So, I don't really know much about genetics.  

If I breed Hope X Chester again, will I have the same outcome? Should I breed her to her brother (Heart) instead?  I know that's a touchy subject.  I don't really have another buck...

Should I keep breeding Georgia X Heart? Or should I try her with Chester?  

And what about my new girl? Which buck should I try her with first?

Ugh, someone help me!
