Oh my, sorry to hear she's got out, I would be utterly devastated if this happened to any of my pets. Have you seen any signs of her today? I presume you've already done this but keep putting food out like veggies etc in her open hutch and run and I'd regularly be going out shaking treat/food bag/boxes too. I'd also think about making posters and make sure everyone in the neighbourhood knows she's missing incase anyone spots her and can contact you. Really hope you find her.
