The project is going strong 254k by 2159 backers. It is now 565% funded and has 10 days to go.
I expect this book to be on efficiency as its predecessor. Here is an example:
I was just searching through books for how much reduction in egg production I can expect during winter months. Not that I am forcing animals to lay more eggs, they are high production birds. Their diet needs to be watched carefully. I prefered to have high production birds instead of heritage breeds or dual purpose due similar reasons why some prefer c.cross for boilers (with aditional reasons such as high quality
compost production and recyling food waste). They are high input, so it is wiser for me to check how much I spend vs how many eggs I get. They produced roughly 80% for the last 2 months.
In "making small farms work" Richard included an excel spreadsheet of egg production. Interesting. He starts with a 500 bird flock in Jan (probably with older birds) and keeps them till the end of september. He expects 25 of them (5%) to die during the season. A second fresh flock is introduced in june (same 5% loss can also be observed). So I can deduct from this date I can expect to have 5-10% animal loss during season. Also I can see that production flactuated between two plateaus. Roughly 65-70% between dec and march and 80-85% between june and septh. So 75% production is what I can expect from layers for the next month.
Interestingly, he also included another table of how much he spent on oyster shells, food, straw, root veg., electric and inspections. There is an excel table included about the time spent for egg collection, packing, maintaince and selling. Frankly I find these data very useful.
This chapter includes other interesting titles too. Such as; how to deal with dead poultry (by composting, explains how), designing an egg mobile (moved by atv) and mobile feeder, building next boxes, integration with pther livestock, selling, feed considerations, how to conduct field surveys (to count insects and such), why pellets, why fish based protein.
Making small farms work is a 300 page book, this book will be over 700 pages. I expect a lot more.
