I've got a doe who's had 5 litters for me; Satin.....first two litters normal, 8-9 kits each, and mom only hopped in to nurse young. The last three littters have been awful...she spends so much time in the box that she has overheated one litter (kindled in hot weather and then her body heat), and seemingly SQUISHED two or three kits in the past two litters. Kits were fine when checked, then dead two days later. Only 3 kits survived on this last litter of 5...any suggestions on what I can do to keep her out of the box when she's not feeding them? I've got a board for her tootsies to rest on, plenty of feed and water so not sure where I'm going wrong.
