I have a six week old mini lop bunny that I had just weaned from her mother. She was the smallest of her litter (but not really a runt because there are no defects, just her size), and she is perfectly normal and most active from the litter. However, I have noticed that when she is standing still it looks like her head is moving with her when she is looking around. It will move around from side to side. Hence why I named her (Daz)ie. Is this normal? I love her just the same but I noticed the rest of my bunnies do not do this.
