Hasbio intended for birthing mares to instinctually handle newborn foals. Now mammuhs are excited to see their babbehs and will lick them clean despite the bad taste, then feed and keep them close. This was meant to make fluffy pregnancy more appealing to owners and to ensure that foals would not die from hypothermia.
1 in 5 mares will fall asleep after birthing with the odds increasing in the case of larger litters. Developers considered this an acceptable margin given the assistance of a special friend and the room temperature of a home.
For ferals this is particularly problematic as any foal landing too far from their mother or warm nesting material may die of exposure.
