That's awful
I really hope it's not true, although they'd still be horrible people for laughing and lying about such a thing
Harvey fell down his hutch ramp, he does powerful flops onto his side and he was in a new two storey hutch and did his flop on the second floor next to the opening to the ramp, hit his back on the ramp, did a backwards roly poly and landed on his feet. So it's definitely happens. He hurt his hip as well and stopped eating
luckily some metacam later and he started eating again
same could have happened to this rabbit, injured, stopped eating and no treatment, which could be a death sentence
