Our Doe kindled Friday night, we had four kits. Last night we came home from church to find that the doe had pushed the box of kits our from under the protective covering we had over her temp. cage. 3 of the kits had already froze to death, we moved her and the last kit inside the house and we thought we had warmed the last one up sufficiently but I found it dead this morning. What can we do to keep our doe from getting mastitis, now that she has no kits?
