The fetal head and neck will be untucked, and are being held level with the spine in the "normal" horse position. Its sex is now viable: you can see that little lumps have formed for the scrotum, if it's a male, or the udder, if it's a female. The fetus is now about the size of a chipmunk. It remains hairless and pale in the absence of pigment.

The mare will be experiencing hormonal changes and increased blood flow to the uterus - now the size of a melon - but will not yet look pregnant.
