Yes they should but only at an appropriate weaning age which is typically around 4-6 months old.
Nothing..
You should, to ensure that the male (if he is intact) will not try to mate with the Jenny. Some donkeys and horses are aggressive to the females while mating.
Mules are "obtained" by a jack (male donkey) breeding with a mare (female horse). Hinnies are offspring of a stallion (male horse) mating with a jenny (female donkey). Mules cannot have offspring because of the different chromosomal numbers between horses and donkeys. See the related questions below for more info.
By mating
There are two types: prezygotic and postzygotic. Prezygotic barriers prevent mating from even happening. If mating does occur, postzygotic barriers reduce the chances that an offspring will survive before being born. One prezygotic reproductive barrier is mechanical isolation.
if a male is separeted during mating it can die
because they bray like donkeys to attract mates during mating season
Mating is the process by which two organisms come together for the purpose of reproduction. It involves the transfer of genetic material from one individual to another to produce offspring. Mating behaviors can vary greatly between different species.
Not all matings result in conception of offspring, so there is the possibility that no eggs will be fertilized. However, if the mating was unintentional, your veterinarian can give your female dog an injection of a "mis-mating shot", which is basically a single high dose of hormones that will usually prevent any fertilized embryos from attaching to the dog's uterine wall.
A mule is a hybrid offspring from the mating of a female horse and a male donkey.
