one of my does had 11 kits almost 2 weeks ago. their eyes are open at this point. i gave 4 to another doe to foster. she was down to 5 kits as of this morning and they were all fat juicy and healthy. late this afternoon, 3 were dead . they keep doing this thing where they burrow down into the nest in different areas. i have been finging them and putting them back in place. the other two litters don't have this problem. the way the nest is built? they are drop down nest boxes. anyway i checked on them and three were buried at the bottom and dead. 1 was fine and the other was fading. so now there are 2 left. i assume it was heat that got them. its july in central florida.
