I got the first egg from my coop of pullets today. They are a week shy of 4 months and there are Rhode Island Reds and Black Australorps. I've always heard they'd lay at about 5-6 months old. Do I need to do anything special for them since they're laying early? Are the RIR's or BA's more likely to be the one who layed the egg? Also, what age did your chickens start to lay? My Barred Rocks layed at almost exactly 6 months.
