All of these males are up for stud and many of them are from my best battlefield teams with 3+ desirable battlefield tactics.  You have the option to pay silver directly or offer trades in the form of gold, premium items, or vermillion.  In order to pay in non-silver currency, post a private sale to me with the agreed-upon trade after requsting the breeding.  I will then buy the item for the same price that you paid to breed my male. Gold and premium items would be negotiable (just PM) and the vermillion prices are as follows:

Unicorns:

 for 1

     for 10

           for 25

Dragons:

  for 20

        for 10

Throdama:

    for 10

Roc:

  for 15
