I am not an expert on breeds, but when I adopted my last lop bunny (not Odette) she had an aeroplane ear. As she aged, her face filled out and the ear lopped. You couldn’t tell she ever had the aeroplane ear. I think lops usually have fully lopped by three months, but your cute litte guy might take longer and may not fully lop at all. Its not dangerous to my knowledge. I think it has to do with head width. I loved her little aeroplane ear. My baby, Manon, lived eight years and never had any further issues with her ears.

Edited to add: Manon was a Holland Lop. Maybe some breeds take longer to lop? My other two lops have been/are mini lops, so they lopped young because of the wide face.

His ears are too long to be a full blooded lionhead, and he also doesn’t have the flatter face that a lion head has. It looks like he has up and down ears, which can be fairly common. It’s where one ear sticks up and the other goes down.  It could be that as he ages, both ears will lop, though.

Since he is 3 months old now, it would really be best to keep them separated, which means no more play time together. Even if the female is too young to get pregnant (right now) since he is entering puberty, the hormones could bring on aggression which could lead to fighting. And it only takes a few seconds for rabbits to mate, sometimes quicker than you can see, so it’s better not to take any chances. Keep them in the same room, but don’t have their cages or pens touching each other. Rabbits have been know to mate through cage bars.

I had a german lionhead lop. He looked like yours when I got him, all black and fluffy with one ear up. I called him a semaphore bunny. As he grew up the other ear fell over. His mane came and went several times over the course of his life and he turned grey when he matured, like a chinchilla.

I think I got him at three months and he didn’t go full lop for some weeks after that.
