I'll be starting 6 RIR's and 6 BR's in mid October. I'm interested in what the experienced BYC members feed thier chicks from day olds thru the start of laying and after they're laying regularly. At what ages do you change thier feed? What about additives to thier water while they're growing? I'll be using the eggs from this batch to grow my flock in about 1-1/2 yrs. These girls are my brood stock and I want the best for them.
