Hello! I went out in the coop today and discovered that, instead of the 2 eggs I've been getting lately, there were three. One looked a bit different - light pink with dark rusty reddish brown spots. I have Marans, white leghorns, Rhode Island Reds, a New Hampshire Red, a Buff Orpington and a Dominique. Any idea who might have laid this egg? Since it clearly came from a breed not known for producing spotted eggs, are they likely to continue, or was this a one-time thing? Thanks!
