Today my sister and I put a lionhead doe in the buck's cage. She's never been bred before, and I am unsure of her age (I think young). He tried breeding, but she wouldn't lift. Then she started lifting her head and falling over. I immediately assumed seisure, or heart attack and put her back in her cage. She just fell over and was making nasty grunting noises, having a hard time breathing, and stretched out and died. It was 22-25 degrees outside today. I bred another doe just before this, and there was no problem there. I cannot see how this would be temperature related. I have no idea what happened. My sister got this doe a week or 2 ago. She seemed healthy and fit.
Any ideas?
