She just passed away last night/this morning..... she has been acting completely normal but there must've been something wrong. Thank you very much for your advice. She was already too far gone I guess..
Her spine and hindquarters feel like a normal-weighted Holland Lop. And yes, she is small for her age. She's eating mostly normal, she gets 1/2 cup pellets a day with a pinch of oats. Usually she just doesn't eat the oats.
I got a 3 month old Holland Lop doe a few weeks ago from a breeder. She has been acting completely normal but her belly seems to be really full all the time. I've never experienced any health problems with my bunnies before so I don't know if it's a concern. At first I just thought she was...
Thumping is usually just a sign of danger...is she spayed? Some un neutered rabbits thump when they want to breed. Is she eating normally yet, and have you tried giving her hay?
The 3rd that says "girl?" looks like a male.. otherwise the others look accurate. How old are they? Also, when you're trying to sex them, press down and towards the rabbit's head. Slit= doe, circle= buck. Hope this helps!
If the water drips out of the bottle into a bowl, and she likes drinking out of the fountain, it sounds like she would prefer a water crock. Make sure you get one that can't tip over easily though.:)
I also agree with Blue Eyes. Breed doesn't matter, but it is usually easier to bond a female and a male (instead of female and female, or male and male).
The reason she's very calm when you flip her over is because when a rabbit is on it's back, it is called "trancing"..... it can be extremely harmful to the rabbit so please do not do it unless you are checking gender, or for health problems.
No offense, but if you "know barely anything about rabbits," why did you decide to get one? Rabbits are animals that need to be researched first, they have a lot of preferences and health issues!
