Well, to me they look like they have potential to be siblings. lol
Lionhead mix. Not all babies would inherit the mane. Just like not all lop mixes inherit the lopped ears. Possibly mixed with Nethie or Polish... but then again, one of the parents could have been mixed as well.
But at least lionhead for sure. Sometimes these things can be difficult. So many breeds have similar traits, especially if they are just "pet quality" in type.
I have a rabbit named Gyda and she has a few breeds in her. One parent was a Flemish Giant/Californian, the other was a Harlequin. Or something similar to that anyway. Who knows what else was further back... the babies in that litter were 3 shades of harlequin, solid black, and lightly cali marked (pointed white). Quite the weird rainbow. A lady sold them to the farm store where I bought them. She worked there and I chatted with her. She said she just liked mixing them to see what she got. xD Gyda is a magpie harlequin in color with a body type similar to that of a flemish giant and weighs about 12 pounds. lol
Here is a picture of her when she was a little younger.
