It means that if your mare does not get in foal or does not carry the foal to full term, then you don't get your money back for the stud fee.
Yes!
in my experience the foal is ussually the size of the sire but that does not mean the foal wont get as big as the dam
No, maybe a little moody but not mean.
do you mean the foal or the dam? usually the foal would try to stand up, snapping the imbilicall cord, leaving the foal non-attached to his/her mother. the mother would then lick her foal dry
it means the mare is pregnant
A 'foal' is a young horse - under 1 year of age. The plural (for more than one) is 'foals'.
It means the horse's foal/s.
If you mean buy a foal, you can buy a weanling at any breeder. If you mean have your own foal, and you do not have a stallion, you can buy a stud service. It is quite easy. You bring your mare to the stallions farm, and he will breed her and you pick your mare up, and 11 months of so later, you have a foal. Usually it is a couple hundred dollars less then buying the horse, so it is a good deal.
A tilly? No clue. If you mean FILLY, it is a female foal.
Saddle
An orphan foal.
It is still called a foal. Sucking foal.
