Grub generator reboot

(mild gross factor warning for very sensitive – grubs)

My “new and improved” grub generator wasn’t working.  The original buckets were better.

YouTube instructionals notwithstanding, the grubs don’t walk up the vacuum hose.  They don’t negotiate the ridges very well.  What they do do, is crawl around that flat ridge near the top of the Rubbermaid, and they have no trouble crawling straight up the sides of the plastic.  They really make time too, it’s sort of amazing.  They’re on a mission.So I bored a couple holes along that flat ridge on either side for them to fall out,And put on a little tray to catch them.My biggest “move” though, was physically moving the thing out of the edge of the woods, to right in the middle of things at the corner of the greenhouse.  The biggest downside is smell.  It’s not as bad as you might imagine (I don’t think), and the smell comes in phases (as do the grubs).  It smells the day before a “shipment” of grubs come, and doesn’t smell while they’re  productive.  It doesn’t smell, it smells…I can live with it. Smell and inherent grossness on one hand… vs. recycling, free chicken food, and high quality protein supplements for my birds – it’s a good trade.

Moving the box of death into the middle of everything is mostly so that the chickens use it.  And boy do they.  They are always around it, keen eyes out for any escaping grub.  Little Pepper is a real addict. Always at the box.  She’s gonna be healthy.

Even in the pouring rain – I was out there slinging water – I saw the teens running over periodically to check for grubs.Grubs teeming out into the tray. Perchick partaking.  I removed the vacuum hose after the drilled holes proved effective.  Not quite there yet, but closer.  It’s an evolution.

And now, something cute:Chicks (teens) cashed out in the heat.

Grub Generator

Warning- gross factor!   This post is about dead meat and grubs, although there are no grubs pictured!

I made a fancy new grub generator.  The original was effective but very, very primitive.

I got this one’s refinements from watching youtube videos, but used a big rubbermaid tub, because I had one, and I didn’t think a big bucket is capacious enough. Plus a few adaptations I made up.

First, the access portal for the flies.  There’s a hole in the side of the bottle.  I assume this is to limit both smells escaping and rain getting into the meat chamber.The flies get in through the bottle to lay eggs that colonize the dead meat.

On the inside of the tub, there’s a vacuum cleaner hose with a bunch of holes cut in it (that part is a bit tough), held onto the side of tub with zipties.  It’s arranged at a slight angle in a spiral around the tub, for the grubs to climb along on their bid for freedom.  Because they do that.  Yep.

It’s a grub escalator.  They will climb to the top like pilgrims, and then drop out, into the catchment bottle.  Surprise, no guru!I found it best to stab two slits through the side of the tub to attach the zipties.   You can see by the zipties on the outside how the vacuum hose makes a full spiral to the bottom of the tub.This vac hose was perfectly suited for this purpose, I’m quite sure unintentionally, and the catchment bottle slips on and off the hose, with a little duct tape gasket, for those days condensation inside the bottle enables the grubs to climb the walls.Best to draw a veil over the current contents of the grub generator.  All the chickens that died of natural causes this winter are in there, now thawed out.

NB: I strongly recommend installing the vacuum hose and zipties…spiraling all the way to the floor of the tub… while the tub is empty, and clean, before putting in the old, dead…thawed…carcasses.  Trust me on this.

The protein of the dead critters will be transformed by the action of the blowflies and other detritivores, their life cycles turning offal into top flight chicken protein.

I’ll leave it to all the other info out there to explain how awesome this form of recycling waste is, and how it helps reduce, not promote unsavory insects, and how much it’s good for the hens.  There’s loads of excellent and thorough info out there, starting with the black soldier fly fan club.  This is just my design, and I’m pleased with it.  I plan to make another to rotate between.

I can just picture my hens lurking around the tap all day.
