SC - Kid Slaughtering age

[grizly at mindspring.com]

Can someone here tell me the appropriate age to slaughter a kid?  I want to find an animal that is still young and milder tasting than an old nanny or Billy.  I have located a source locally for yearlings and new birth this year.  I'm gathering info about slaughtering and ages and the like.  I'm going to avoid wielding the knife myself since the aprtment managers would frown on it.
