All rabbits produce two types of poo -- fecal and cecal. The fecal poos are normal poos and tend to be greenish-brown or brown and are generally the size of cocoa puffs cereal. They will get harder as they dry out but should crumble when pinched (once they are dry).
The cecal poos (cecotropes) are the ones that a rabbit will eat. Cecotropes are not feces and are produced in the cecum. Cecals are clustered, smelly, and moist (covered in a mucus). They eat them directly from their bottom. Normally one does not see cecotropes. However, young rabbits are still figuring out that they need to eat those so it isn't unusual to see those clustered cecal poos on the floor (and perhaps smeared as well).
Here are a couple articles on this:

When rabbits are stressed (like moving to a new home), their poos can get out of whack. It is good to be monitoring them as you are. Feel free to post any photos so we can see if anything looks alarming.
And just so you can better see the eating of cecotropes (or rather how one does not actually see the cecal pellets) here is a video showing one of my rabbits doing so.
