KISS
Yeah, the essence of what Bob was teaching the beginners holds. Keeping huge numbers of birds, ending up frustrated and unable to focus, unable to afford the feed bill, disinterest, etc. These are the things that make for what Bob used to call "Here today, gone tomorrow" hobbyists. Bob also taught that beginners need to know where they can get birds from a partner, should something catastrophic happen.
If I put 80-100 chicks on the ground and I only keep, in the end, 2 great males and 4 or 5 great females, I can turn around the next year and easily put 80-100 chicks on the ground again.
1 female, laying 20 eggs per month. 5 females laying 100 eggs per month. That's alot of eggs in just one month.
I am very biased to quality. It takes quantity only in so far as it leads to quality, if that makes sense.
