Here are my 4 Starlight Green Eggers from TSC. Picked them on April 12 - 6 days old. 3 are yellow and 1 black. Ignore the gray chick - she’s a Blue Rock. They are a bit skiddish but beautiful birds.
Good catch. The Starlight Green Egger is a cross between a Prairie Bluebell Egger and a brown egg layer. The Prairie Bluebell Egger a cross between an Araucana and a White Leghorn.
