Well you see James there is this birds and bees thing...
They never lied to me about that either. Sex is a taboo to children precisely because the parents make it a taboo.
I dunno about that one.
Our rooster hops on top of the chickens all the time, and the goats are just... goats.
When the children ask we tell them they are breeding. If they ask more we tell them "That's how baby chicks come about, and baby goats etc."
When the questions come about people "breeding", we tell them it is not "breeding" like with animals, but a gift from God from married people. Then we talk about the Miracle of our savior's birth without breeding etc.
Not taboo, just part of the creation.
Tabooishness (LOL) exists when people bring perversion into the matter.
Also please remember, just not talking about something doesn't make it taboo. There are things that are private.... Of course unless you want your parents to stop closing the door
