I wuld sort of be inclined to say don't react too pre-emptively. It might be that she just needs some time to settle. If she is not in stasis and is still passing a moderate amount of poo then maybe its worth giving her a chance to sort it out herself?
I know you've had really rough times with them and I know that it can be hard to find the balance between the confidence of giving them some time, and knowing when to act before anything catastrophic happens. Owning buns is not easy.
An example being that my Dusk had spurs (over Easter weekend). Wednesday he ate less than usual. Thursday I took him to the vets, and the vet booked him in for a dental on Saturday. Friday he wouldn't eat much but would eat some. Saturday he had his dental and wouldn't touch anything. Sunday he hardly touched anything and I didn't want to syringe feed him as much as I should, so I gave him a small amount. He was hardly passing anything, and had I taken the vets advice from the dental, I should have taken him back to the vets that day, but I chose not to. Monday, he wasn't much better, but there was some improvement, again, not enough and I probably should have taken him to the emergency vets (Easter Monday). Tuesday he was his normal bouncy self. I had to make choices based on Dusk, as opposed to based on rabbits in general, and I knew that a vet trip would stres shim more and make him more off his food. I used the tactic of putting him next to other rabbits in the runs and allowing him fresh air, and just giving him enough to keep him ticking over until he was ok.
I'm not saying you should wait, only you can make that call, I'm just illustrating, that sometimes waiting can work out ok. Obviously there are times when it doesn't, but that's down to the owner to decide what's best for their animal.
What do you think is in her best interests?
