Let me tell you this....
When I first got Madilyn, my black female Lionhead, she was GORGEOUS. I really wanted her just because she was a Lionhead. I really do love the Lionhead breed, not just because of their looks.
I brought Madilyn home and she was curious, funny, smart, and always made me laugh. I got her spayed about 2 weeks after, bonded her with Mallory about a month later...and now she is a total jerk. She wants nothing to do with me most of the time. She is still a really lovely rabbit, maybe not perfect to the Lionhead standards, but her personality is one that I am not fond of. I still love her deeply though.
Marlin....he is a Lionhead. He is still a baby at 16 weeks old and his mane is just lovely right now. I know that he will probably end up losing most of his "fluff", but I don't care. I still love the little guy.
When I went to Peg's house, she had a ton of Lionheads (of course, hehe)....to be honest....some were just plain ugly. Those ugly ones though, were so sweet and such wonderful rabbits.
In my honest opinion....the ugliest of the rabbits are always the sweetest. Kind of like humans in a way. In school...the "band kids", or "geeks", or "the uncool crowd", or "the gothic kids", or the "ugly/horrible dressed people"....are always the kindest, most true, and loyal people in school. Why? Because no one gives them a chance and always makes fun of them. Notice that the "best dressed" or "most popular" people in school are almost always the nastiest people.
Again, my point....looks are not everything in rabbits. Same goes for humans, horses, dogs, cats, snakes, rats, ect. You need to follow your heart and pick the rabbit that you are most fond of. It seems like you are taking more of a liking to Lionhead #1....go with her, if that is what your heart tells you.
Just don't forget about Pixie, your first baby. Think about her emotions in this case as well. She is probably going to be quite jealous of the new bunny and might take her anger out on you, also because she is going through puberty. I honestly thing Pixie should be spayed before bringing another rabbit into the home. It could really stress Pixie out.
Keep in mind that I am not targeting you. I am telling you my honest and straight up opinions, because honest opinions are important right now.
