A foal is usually only called a foal for a year. Then they are called yearlings.
The gestation period is eleven months.
Mares typically stay pregnant for 11 months, but may give birth up to a month early or late.
All things being equal...good nutrition, and a pristine uterus in a mature, young mare lends itself to earlier foaling. Older virgin mares can be more problematic. A bred immature mare/filly can go longer. Generally a minimum of 310 days will result in a viable foal, if the pregnancy is normal (no infection, body pregnancy etc.) Nominal is 335-345 days... Mares can go a full year in foal under certain circumstances and produce a healthy foal. Plan for an early foal...first foal mares can foal without developing an udder...hope for around 335-345 days.
After 11-12 months, she will drop her foal. To say, it will be born. Mares normally foal at night when she is safer from predators. In the wild, she will stay away from her herd for about 10-14 days in order to establish a bond with her foal. If they foal is exposed to other horses too early on in life, the foal will be confused as to who its mother is.

The gestation period for a raccoon is 63-65 days.
yes
yes as any mother and foal would!
The gestation period of the gray fox lasts approximately 53 days.
Fillys can show heat as early as 6 months. That being said immature fillys will generally cycle sporadically or produce what is called a persistent follicle that limits their ability to get in foal even if bred. Two year old fillys will often cycle regularly.
