Now that's what I'm talking about! I'm so in love with those dark mahogany eggs!!!!
Yes, it is possible that the dark brown speckled egg is from Esme - even though she has the beard, muff, and pea comb. These barnyard mixes can be any combination of the different breeds and she seems to be showing the Ameraucana and Marans, but apparently there is something else in there as well (if she is laying the brown egg). One time (but only one time, so it'd be pretty unlikely), I had a similar instance where an Ameraucana look - alikeEaster Egger layed a brown egg for her entire first season, molted, and then layed a slightly green tinted egg. It was sort of freaky really. I personally love the dark spotted eggs.
Can't wait for photos of the girls.
How's the smoke up your way?
