I’m not sure what you’re asking. Is that a picture of a nest? If you’re absolutely positive they are both girls (mistakes happen more often than people think), then it’s likely just a false/pseudo pregnancy.

If there are no other signs, I’d say this is normal behavior for an un-pregnant rabbit. Rabbits like to dig and rearrange in their living quarters (and in other places as well). If you give them plastic baby keys or stacking cups they tend to like to toss those things around. So this is not a behavior that means a rabbit is pregnant.

If she actually is nesting, the babies will come very soon. Rabbits typically don’t nest until the day – days just before giving birth.

If it’s a false pregnancy it will resolve without intervention.

If it’s just normal digging and rearranging behavior, it will probably just go on. My rabbit is spayed and very fond of digging, esp in the sofa.

This can be normal behavior, especially since the cage as a plastic, slick, bottom, so sliding and pushing hay is going to happen pretty natural.  Note if you have two intact female rabbits together (assumably young), they likely have what’s called a baby bond, which is a false bond which can dissolve quickly and rapidly upon one of them becoming hormonal. It can lead to fights/injuries in an instant when that happens, so for safety and prevent accidental pregnancy (in case one is missexed), please separate them both from each other and have them spayed, and then you go through the proper bonding process after one month – https://binkybunny.com/infocategory/bonding/

Note that rabbits do not have pads on their feet like dogs and cats, so they are always wearing fuzzy socks. They need appropriate flooring (i.e., not plastic/tile) or else they cannot move comfortably nor exercise well.

I agree with the others. Just a pile of hay doesn’t mean anything. Rabbits like to push hay around and dig. Without the actual nesting behavior accompanying it, I think it’s probably just normal rearranging of hay.

All three of my first rabbits where female and they would rearrange or nest even when not pregnant sometimes they would pull out there fur to add to the nest. Don’t panic. It’s normal for them to do this sometimes, especially at peek hormonal times.
