Like it or not, a big part of life is killing things. Weeds, ants, wasps, mice, moles, groundhogs, burglars... It isn't fun, but it's gotta be done.
Hell, when I moved to this place I reread "Living on a Few Acres" and some hippie Little House on the Prairie Readers Digest book my parents got when they did something similar when I was little. Vegetable garden? Plant your seeds. ...Go through and weed out 1/3 of the smallest plants... When the chicken stops laying, here's how to kill and clean it... Pigs...tasty. Goats, cows, and other milk animals need to have babies periodically to keep producing milk. But you don't need a bunch of baby animals so off to the slaughterhouse.
