Have you tried any other types of grass hay (orchard, meadow, brome, oat, Bermuda)? I recommend, if you haven’t already, that you wash the vegetables down thoroughly before serving them to her – that will get more water into her. To be candid, rabbits generally do get a lot of their water through their greens anyway, so keep her eating those (wet) vegs. I don’t know how to interpret those squeaking noises – from your description of her behavior she doesn’t seem to be in any particular distress/discomfort.
Idea: Have you examined any of her poops (breaking them open) to see if she’s excreting any of that window mesh?
Keep monitoring her; if she stops eating/pooping completely at any point or starts exhibiting behavior that’s consistent with pain/discomfort (such as retreating to a corner of her hutch/cage and assuming a hunched posture), then you need to contact a vet ASAP. Actually, as I said in my previous post, I think you should find a vet in your area who knows about rabbit health and consult with them in any event, describing the incident and symptoms as you’ve been reporting them to us.
