I went to feed the critters last night and found three dead kits in one of the hutches. The kits were almost 6 weeks old and appeared to be in good health during the morning feeding (less than 10 hours before). The doe and 2 other kits appeared fine and were doing OK this morning. I've seen single kits die before but 3 at once has me stumped, especially with no sign of sickness or problems. The kits were growing nicely and were very active. None of the kits seemed lethargic or sickly. No changes to feed or routine, clean cages and water. Ruling out bad feed / water as the others in the rabbitry are OK...so far. The kits started nibbling on solid food about a week or so ago. I've always let the little ones eat when they are ready and haven't had any problems like this. I up the feed volume by 1/2 cup to compensate for their consumption. My only thought is the doe may have become agressive because the kits were competing for feed. This particular doe showed some agressive tendancies in the past. I checked the dead kits but didn't see any obvious bite or claw marks. Any thoughts??? I'm plain stumped on this one and am worried about the rest of the rabbitry.
