My housemates and I are fostering a mama rabbit and her 3 three-week-old babies and I was wondering if I should provide them with pellets free choice or whether I need to take them out for part of the day. They seem to be munching at the pellets (Mazuri Timothy based) and emptied their bowl sometime in the evening. Should I just keep filling it and let them keep munching? They seem to not be nursing anymore that I can tell. Thanks!
