Can you identify these chicks??
Chicks get put back into the wrong bins all the time at feed stores. Sometimes, if there are only about 5 left in a bin, they move them to another bin but don't change the labels. You've really got to know your chicks and what's what when buying feed store chicks. The labels on the bins and the people who work there can't always be trusted.
As for gender of the Easter Eggers, it's too early to tell by looking at them. Odds are that at least one is a boy. Easter Eggers tend to be one breed that is more difficult for hatcheries to accurately vent sex.
