No it is not possible biologically for a human to impregnate any other species or viceversa. So to answer your question simply, "No a boy cannot get a female pony (mare) pregnant."
A Fell pony can be a male or a female.
If it is male then it cannot be pregnant.
A female horse or pony is called a mare. And a boy horse or pony that hasn't been gelded is called a Stallion and a boy horse or pony that has been gelded is called a gelding.
If the male's sperm comes in contact with the females vagina, the female can get pregnant.
breed it with a boy rabbit
No. There is no possible way for a guy to be pregnant. He may have been born with the boy genitals and converted to female genitals and now looks like a woman, but he cannot become pregnant. It is only possible for females to be pregnant (if you are human). As for animals, I'm not 100% sure. I know that male sea horses get pregnant and the female sea horses do not.
The Dartmoor Pony is a FEMALE.
Not that I know of. All the pregnant ones I have had have been female. I highly doubt that a male one can.
You can't. Only female mammals - and cats are mammals - have the required body parts to get pregnant.
to get the female hamster pregnant you have to have a male
A baby pony is called the same thing as a baby horse, a foal. A male foal is a colt and a female foal is a filly.
No because if you kick the stomach the pony will get mad
