To be able to breed your tiniquine, first of all it has to be a mare, even if you are studding out your stallion the only thing you'll get from that is a breed fee if he's registered. So if you are trying to get more tiniquines that won't do you any good. Your tiniquine has to be a mare.
Breeding two registered tiniquines:
Once you have a registered mare if you have your own registered stallion then there's no problem. Once she is of breeding age, or if she already is then you can just send in the breeding form and she'll be bred to your stallion. If you have a registered mare and don't own a stallion and you want to breed your mare to a registered stallion then you need to look through the registered stallion stud book to find a stallion up for stud, how he is currently standing (open, limited, reserved), and what his stud fee is. Once you have found a stallion with your requirements then you need to email or contact his owner and see if you can breed your registered mare to him. Once you have an agreement and you have paid the stud fee then you need to send in the breeding form and your registered mare will be bred with the registered stallion.
Breeding two unregistered tiniquines:
If you have an unregistered mare and you want to breed her to a registered stallion the same actions apply. if you own the stallion then you can just send in the breeding form and get them bred. If you have an unregistered mare and don't own a stallion and you want to breed your mare to a registered stallion then you need to look through the registered stallion stud book to find a stallion up for stud, how he is currently standing (open, limited, reserved), and what his stud fee is. Once you have found a stallion with your requirements then you need to email or contact his owner and see if they even allow their stallion to be bred to unregistered mare at all, some won't. But if they do allow it then you can pay the fee and send in the breeding form and they will be bred.
To find the rules about registering a foal from one or both unregistered parents see the Registration section.
Note:
Not all owners will want to breed their stud to all mares. Owners of registered stallions may or may not let them be bred with unregistered mares, despite the stud fee. Some will only let their stallions breed to mares of certain color. Some will only breed their stallions to mares that have a good show history. Owners base what mares they allow to breed with their stud on their own criteria. So if you want to breed a mare to a stallion but she doesn't qualify to what his owner is allowing to breed with their stallion you'll have to find another stud or not breed your mare. Hassling the owners to give you stud rights will only bring trouble. If they say no it means no, end of story. Just be aware that not all owners will let just any mare breed with their stallion, for whatever reason.
Once your tiniquine(s) is/are up on a page and you have all of the stats down and a visible link back to ShadowFlight Stables, only then may you breed your tiniquine(s). Once that's done, wait for breeding slots to be open at the forum. If breeding slots are open at the forum, then you may post your breeding application there and have your tiniquine bred to get a foal.
