And here... type, color, correctness, brick shape, etc... that all gets you nothing if you don't lay an adequate number of eggs.
I grind, mix and ferment my own soy free, non-gmo feed (in addition to BSF), so I charge a premium for my eggs.
The demand is there since so few folks around here provide this type of egg, so egg money for me is what offsets my other poultry expenses.
But we have three rules around here 1) that each type of livestock must at least support itself plus feed us, 2) you have to have shoulders (this came in handy when the kids thought snakes should be pets), and 3) you have to have a job (this is true for humans and animals). Every animal has a purpose, otherwise it isn't allowed to stay. That goes for everything from barn cats to grow children.
My meat sheep have to be self supporting with enough extra to support the dairy sheep.
My beefers need to support themselves and my dairy girls.
My production layers support my Heritage RIR.
Haven't figured out if the Rhodebars will make it yet in our financial requirements eventually, but we'll see... I'm thinking my production layers cannot support both the HRIR and the Rhodebars, so I know the Rhodebars will be a financial loss over the next few years.
We put pen and paper to it regularly... if we break even on each type of livestock we consider that a win.
Since we consume our own beef, milk, lamb, eggs and chickens then breaking even on paper without charging ourselves for our own food means no grocery bill... another win.
