Just be aware of this:::
[SIZE=14pt]Jacks (males) can be fertile at one year of age, sometimes earlier, sometimes later depending on when their testicles descend. The famed herd sire "Charlie Bandito" owned by Pheasant Meadow Farm in Maryland, produced his first offspring at the age of 12 months and his first son, "Guido Bandito" produced his first offspring at the age of 12-1/2 months. BEWARE: We've had two letters now in Miniature Donkey Talk Magazine of 7 month old jacks reproducing![/[/SIZE]B]
And This:::
[SIZE=14pt]If the jack has descended testicles, he can reproduce and many jennets start producing eggs that can be fertilized at 9 months of age so obviously you cannot pasture these two animals together. (Miniature Donkey Talk Magazine has published two letters from owners confirming 7 month old jennets becoming pregnant.) If you allow such a young jennet to become pregnant you are asking for big trouble (see above under reproduction). Not to mention, your reputation as a responsible "breeder/owner" will be ruined.[/[/SIZE]B]
So he may well be ready and jumping on a Human is sure not what anybody wants but He may Also be Matureing and SHOULD BE watched VERY carefully and with lots of caution~
