I've been feeding my bunnies Burns Green Oat Hay for the past couple of weeks (they had it before but only occasionally). But now their poos have gone black, a bit smaller, kind of shrivelled, and rock hard (impossible to squish to see if they're golden in the middle - believe me I've tried!)
Should I change back to Burgess Forage timothy hay so they get lovely golden poops again? Or are black poos ok?
