I know others have posted this before, getting an egg like this on occasion or from a new layer, but I have a buff orpington pullet that has been laying for a little over a month now and consistently lays eggs with these white spots on them. Sometimes just a few spots, sometimes loaded. There is texture to the spots, but do not flake off. I've tried to wash them off and all they do is turn dark when I get them wet and go back to white when dry. None of the other pullets are laying eggs like this and they are all on the same diet. I thought she'd outgrow it but no such luck. I'd like to start selling some eggs but don't want to sell hers looking like this (personally it doesn't bother me but you know how people can be). Any ideas why she is laying eggs like this and if there is anything I can do nutritionally to stop it?
