Chickens and Grubs

Don and I are avid composters; Don probably more than I am. He reminds me of that old nursery rhyme about "snakes and snails and puppy-dog tails." Sometimes the more disgusting a project is, the more he seems to enjoy it. He likes to take care of and feed our kitchen composting worms, for example.

Actually, a properly-managed compost pile is far from disgusting. When well managed, compost piles do not smell unpleasant at all. But they do harbor a variety of bugs, microorganisms, and other things that I am not enough of a scientist to explain. Don seems to revel in this, particularly in the grubs.

Honestly, I think he revels in the grubs for their own sake ("snakes and snails..."). But he also likes to spoil our pets, and our four laying hens love nothing better than insects, particularly goodies from the compost pile, and especially grubs.

We are lucky that our climate is in "Zone 7" on the climate maps, which means that we are in the northernmost range of the Black Soldier Fly. These flies are voracious at eating up kitchen scraps to the point of being scary in a B horror-movie sort of way. And they make fantastic nutrition for the chickens, converting the kitchen scraps to fat, protein, and calories, which our dear hens then convert to eggs for us and fertilizer for our compost piles and garden.

Then the garden waste and kitchen scraps go into the compost pile, which then grows new larvae right up until the weather gets too cold for the soldier flies in the fall. Don has discovered that if he puts a big pile of "green" type kitchen scraps in the compost bin when the weather is warm, then covers that with a good layer of sawdust so it doesn't smell, then puts some chunks of fresh pineapple with the moist side down on top of the pile and the hard shell of the pineapple up toward the sky, then he can harvest black soldier flies by the handful (I shudder) to feed to our "girls," as folks in the U.S. call their chooks (a British or Australian name for backyard hens).

I jokingly call Don their "rooster," because he brings them the choicest (to them) morsels and tries to make sure all the girls get their fair share, despite their jockeying and pecking order. And, believe me, they watch him closely and follow him around the yard, especially during composting season.
