Every morning before I go to the kitchen for breakfast, I call out my bunnies, lie down in my bed, and have them jump on top of my chest to ask for food. I'd give them some pellets for breakfast right there and watch their little moufs chew for 10 minutes, then depending on their mood I'd either pet them for a bit, or watch them jump and zoom around the room.
This is almost always the best part of my day; every day I wake up half an hour before I'm supposed to, just so that I can do this :)
The ones in the picture that look like cocoa puffs are not cecotropes, but their regular poop. Instead, cecotropes look almost exactly like blackberries. Fun!
They still eat their regular poop all the time though, so if safety is your concern, I think you should be fine!
