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.
