I have 2 Rhode Island Reds, 1 Buff Orpington, and 1 Barred Rock. All of my chickens are laying brown eggs, except for the Barred Rock, she just started laying 2 weeks ago and has been laying white eggs. Any ideas on what causes this? Is it possible that she is not a pure Barred Rock, but rather a BR mixed with something else?
