I have been keeping Guineas for nearly 9yrs now and I only have one sow on her own due to her attacking everyone else, she acts like a boar. Are you sure you have the sex correct on both your sows and they aren't infact to boars?

When guinea pigs fight, they chatter their teeth and a 'war dance', what you are describing is a dominant sow showing the other one she is the boss.This is a typical behavoir when introducing any pigs together. The wheeking sound the less dominant pig made is a scaried noise but she will get used to the other sow being around. All I suggest is you keep trying and putting the together, put plenty of food around the cage, not specifically in the bowl because the dominant sow is defending that.
