I got some dry hay. She's not eating it.
Do you think chopping it to small pieces would help?
Good news, well done!
She's upset right now and maybe scared everything she had over past few days caused troubles so she maybe don't trust food anymore. Here are many people with years of experience with rabbits and can probably suggest how to make her eat hay again (if she was on hay previously as was said by other people on this thread she maybe had fresh grass or what you have locally there). I only have a few months of real experience with rabbits, but I have four from 8 weeks of age so a bit of experience with juniors.
I also made some mistakes I gave my first rabbit 8 weeks old some Iceberg lettuce I didn't know it is not good for him and he was unhappy next day and his stomach was bloating but I watched him and learned that Iceberg is bad and also that he's generally too young to have much greens or vegetables, I gave him a full carrot too, and a half of an apple. I was generous
He is a very strong rabbit and after I noticed his belly is big and he's not eating and not very active I just stopped giving him vegetables for a couple days then learned which ones are good for him and was very careful after that. He never had any problems after that as he's getting proper food, you can always see if rabbit poops well he's healthy.
With my other rabbit girl she had false pregnancy when she was about 11-12 weeks she started pulling her fur and built nest with hay and fur in the corner, but it was just a few days and after that she was back to normal but maybe that was too stressful and she got sick after that she couldn't control where she urinates and she was all cold and shaking and her fur looked like oiled as she didn't clean herself, was horrible time I didn't know how to help her, she had no diarrhea but some softer poops and I was very scared I thought she might be dying. I gave her some dried herbs every night a little - less than a handful of mint, thyme, chamomile flowers - I dry my own herbs for herbal teas for myself so I use them as medicine for myself so I had some. I made her some chamomile tea and gave her in her bottle half tea half water and she drunk (but I was lucky as not every rabbit would drink) it was good for her stomach I wrapped her into a blanket and held her on me for hours she was very weak. When I put her back to the cage with the blanket she peed on it I changed it often, I think that her plastic floor was cold and I covered with cardboard she peed everywhere I changed it to keep it dry, she also bit me every time I tried to touch her or give her food, I was all covered with bleeding scars. She was very scared so was I, I honestly thought she is dying.
It started on Friday and vets were closed so it was a horror weekend I made an appointment with vet for Tuesday but she was much better and I canceled it, and after a few days she was fine and happy, ate well and pooped a lot, she's all good now but I don't let her lay on her plastic floor put cardboard box and hay and made a wooden shelf for her so I was so scared
So your girl will be fine hopefully, I know vets are very expensive and now is weekend but you are doing good for getting her hay and rabbit pellets, hopefully she will start eating hay, as far as I know hay must be 80% of rabbit's diet (or grass as other people said above, just they are getting hay mostly it's probably easier for their owners when they live at home not in nature) and only 10% dry pellets and 10% of vegetables/leafy greens but you have to introduce to vegetables slowly after they are about 6 months. But sometimes you can try earlier but very carefully, one type of vegetable at once and a very small amount.
By the way, there are two types of poop maybe you don't know yet, usual dry berries and they also produce some soft smelly poops and larger than berries you normally don't see them because rabbits eat them they need them for their health but when they are sick or upset they maybe forget eating them and you can see them so don't be scared. But normally she should make lots of dry berries when she gets suitable food. If she will start eating hay she will get better soon. Well maybe there are some tricks to encourage her to eat it, hopefully she'll be alright
Where did you get hay and hay pellets for her?
