Can raising birds for meat and eggs without always buying more be done on a small scale?
That question is answered by how many folks you're feeding vs. how long it takes to grow out a chicken to be a decent sized table bird. Our "layer" flock of Black Javas produce a decent enough carcass - but take 20wks to mature, 26wks to mature to lay eggs - at least 8mo to get good eggs. They have laid consistently for me - even through the dead of an Illinois winter. Not all breeds still lay in winter.
We obtained an incubator this winter - and am now hatching eggs to grow our flock of hens. (Fox attack last fall reduced hens to lower than what I desire). However, of the 5 eggs hatched, I ended up with at least 3 roosters, maybe 4! So those 4 will be treated well and become table birds, unless one becomes head Rooster - either way, I've got 4 birds for the table. One bird provides enough meat to do a HUGE chicken and dumpling dinner (9x13pan and 7x11pan) - but realistically, they lack the large double breast of a cornish cross for something like chicken on the grill.
If your family favors white meat - you will need to grow cornish cross for the table. If your family favors dark meat - most "dual purpose" birds will suit you fine. But don't grow a dual purpose expecting cornish cross white meat. It's not there!
Because photos are worth more than words, here's a post I did of the three different carcasses prior to cooking.

I hope the photos help!
If you are seeking both eggs and meat for your table - figure out how many times a week you eat chicken multiply that by at least 20wks = that equals how large of a sustained flock you need to have 'on hand' for the table alone. The eggs are harder to figure, if you do seasonal baking. Different breeds lay at different rates - read as much as you can and ask lots of questions on the different sections of the forum to learn more. Please remember, each hen is different, so your results may vary! You can figure on growing out some each month and processing each month - it's very possible. We're not quite there yet (fox attack), but got close last fall. Good luck!
