Version 1.0 of Minecraft added baby animals and breeding. So now I've begun animal husbandry, and I'm off to a good start, I'm just growing impatient with a few of them. Specifically, they won't grow up.
How long will it take my calves, chicks, and piglets to grow up into fully murder-able cows, chickens and pigs?
On a related note, how long do I have to wait after breeding a pair of animals before I can breed them again?
