Um, only sort-of.Looks like it with the white ear lobes which also means white eggs.
Earlobe color can help you tell breed, and breed tells you what egg color to expect.
But white earlobes do not always go with white eggs.
For example, the Cream Legbar breed has white earlobes and lays blue eggs, and the Penedesenca breed has white earlobes and lays brown eggs.
Yes, more often than not, white earlobes go with white eggs, but it is least useful when dealing with mixed breeds (Easter Eggers and Olive Eggers are mixed breeds for this purpose.)
