I know a fair decent amount of 'adults' that will, and do, abuse their goats.
In fact, I only know ~three 'kids' who own goats (under 18), about ~10 under 21, and 50+ over 21. In my observations, they all have a percent who abuse their goats, and a percent who care for them.
Hell, my dad even runs her more irresponsibly than me!
