Unfortunately yes. The lighter cream colored one is a cockerel same as the gray one. Are you sure you can't free range them either? Chickens can live off free-ranging pretty well finding their own food. But during winter months won't be easy because their won't be grubs, seeds, and grasses that they can't consume. My own advice that I have learned is, don't get too connected to your chicks in the future for the first day until they are at least 2-3 months old. So save yourself heartbreak because of too many males.
