three yolk sacs means three babies.
Yes, mammals have yolk sacs. Although they may not be as easily noticeable as the yolk in a chicken egg, it is still there. The yolk contains proteins and fats needed for the embryos further development.
yes
could mean that there were originally two zygotes in you and you would've had twins. or maybe your sac tore during delivery so there were two pieces. I've heard about it happening though where two sacs came out but only one baby.
clarify yolk
that means your bunny is a GUY bunny!??!?!
I am pretty sure because that is how my twins are at the moment that one placenta and two sacs mean identical twins more often than fraternal and more often identical if they are the same sex
A fertilized egg's yolk provides all of that embryo's nutrient, it also provides protection to the embryo. There are two types of yolk, white yolk and yellow yolk, both having their purpose.
Yoke is the correct spelling if you are referring to the yoke that is put on farm animals. If you mean in an egg, it is yolk.

Apparently, there are two babies.
A yolk sac is a precursor to a baby, usually yolk sacs are seen at 5 1/2 weeks. A fetal heart is detectable in the 6th week - that is what is a better indicator of having a baby, eventhough it is called an embryo at this point.
