Can I keep 3 roosters and 25 of same breed together?

Conventional wisdom says to wait until a bird's been laying a month or so to incubate her eggs, just to let the eggs get up to size and allow her system to work out any glitches. Pullet eggs are often fairly small and I'd wait until the egg size was medium or large (depending on the breed) before I incubated. Small eggs = small chicks and that's not good.

Awesome! Thank you !
