Bun eating poop pellets (not ceco)

Halequin is eating her poop pellets and at times this can be quiet obsessive and for quiet long periods of time. She’s not picky and has been going on for a few days now. Any one any clue as to why?

I have tried looking up online but only info is really on ceco eating.

One of mine does occasionally but not obsessively, just a few at a time every so often. I just put it down to a lack of something in her diet at that particular time, she's healthy otherwise.

I had a bun that once did that, never found out why tho sorry x

Iv not done any thing different since we got them except started to change their pellets but they are better quality then what the breeder gave us to bring home and we’re only four days in so still getting some of the old pellets.

She even ignores the hay and searches through it for them.

Beauty is not doing it so I’m completely at a loss.
