I can't find my folder with all my dates and measurements, and Mrs. ruck_feddit isn't here right now to find it for me. All of this will be from memory, but I promise my approximations will be pretty spot on. The bird weights are all of live birds. Put them in a pre-weighed plastic cup so they hold still, and stick it on a scale. I didn't want to order eggs online. I found a nice little old man about 1.5 hours away from me on craigslist. I paid $3 per male and $4 per female and left with around 16 birds. If I had to guess, those birds were about 4 weeks old. In 2 weeks, the first eggs started to show up. In 2 more weeks, each hen layed an egg pretty much every day. You want a 5:1 ratio of girls to boys (I think I had 13 girls and 3 boys to start). Here's a common misconception: Big birds come from big eggs. This isn't really the case in my experience. Big eggs hatch birds that lay big eggs, and big birds lay eggs that hatch big birds. You want to combine these 2 features. My first birds weren't world record sizes: males averaged 11oz-12oz, females 12oz-13oz. Eggs averaged about 9 grams. I save eggs for 5 days before sticking them in the incubator. To start, I only incubated eggs over 10 grams (not the huge double-yolkers, they don't hatch). Once those birds were laying eggs, I kept only the largest as breeders. After a couple generations, I had 12-13oz males and 13-14oz femails averaging 10.5 grams eggs. Fuck yes, but I wasn't done. A few more generations got me males averaging 13.5oz and females 15oz (or even the occasional 1lb beast). Currently, my eggs are 12+ grams with double yolkers up to 20 grams. https://files.catbox.moe/z67d1h.jpg - I wanted to eat birds during this process, so I would separate the "breeding" eggs from the run of the mill ones doomed for the freezer. The small container is lower, so they don't look much bigger. We're only talking a couple grams difference. https://files.catbox.moe/43db14.jpg - Here are some runty ones next to what I'd call average size. Look at all that leg meat! If you started with 10F and 2M, saved eggs for 5 days, and started incubation, expect to put 40-50 eggs into the incubator. You should end up with ~25 adult birds (on the low end) ready to lay in 10 weeks from the day you started the incubator. By the time those 25 are laying, you could have 10 more sets of ~25 birds at 1 week intervals following them. Nothing, including rabbits, can produce numbers like this. **In just the warm months of the year, those dozen birds can put 700+ birds in your freezer.** That's easily over 300lbs of quail meat and an obscene amount of eggs. I only keep ~15 birds through the winter. That's 70+ eggs per week. In the spring, I can jump my breeders up to 75 birds (60F:15M) very quickly. This produces 4-5 dozen eggs each day. Even being super selective gives me 200+ eggs over 5 days to incubate. You can do all this in your backyard without your neighbors even knowing about it. If any of this is unclear, I'll do my best to answer questions.
