My chicks are 9 weeks old. I was looking for a different feed company and on the BUckeye Feed site it says this: . Provide clean, fresh water and grit free-choice at all times. Restrict lighting, if possible, to less than 13 hours per day when pullets are less than 20 weeks of age (some strains of leghorns will reach sexual maturity at 18 to 19 weeks of age) to discourage premature egg laying and the possibility of blowouts I turn a light on once it gets dark and shut it off in the morning! Do I need to get rid of the light for now since it doesnt get dark until 9?
