Hi and welcome to the forum! For future reference, "Bunny chat" is where people post messages using the voices of their bunnies, like complaining about their humans not giving them enough treats, or taking their pictures too often, that sort of thing. It's kind of a fun place that actually isn't chat about bunnies. General rabbit questions usually go in "Rabbits Online Forum" and a health/behavior question usually goes in "Questions about nutrition and behavior". I know this forum can be a little confusing as to which section to post in, so no worries!! A moderator will probably move this thread to the correct area for you.
As for your questions, I always clean up the soft poos (called cecals) when I see them, because they usually won't eat them if they didn't eat it coming out, and they can step in it and get messy. You might want to look at our topics on healthy diet to make sure her diet is good so that she doesn't have too many cecals. Here is the Library article on Poop:

I know too much protein or carbs in the food can lead to cecals--if I give my one bunny too many treats or pellets, he doesn't eat his cecals. This is a great resource about diet:

Head shaking can be one of a couple things. I'll tell you the bad ones first, then the good ones. It could be ear mites, which are little bugs that live in the fur and the ears. Here's the Library article on ear mites:

So you might want to take a look in her ears or have your vet do it and see what's going on in there. The other option is that she's doing a happy dance, also called a "binky." Binkies look like an ear flick side to side, a jump in the air, maybe kicking their heels up. It's hard to describe, so I'll point you to the Library article on that too:

Again, welcome, we'd love to see pictures of your bunny Kitty and talk rabbits!
