My Barred Rock started laying four days ago and has now given me an egg everyday since and now they are up to a grocery store large size. Yesterday someone else decided to give me a gift so the question is who?? Light brown egg is from the Barred Rock and the new smaller darker brown with lots of speckles is my new layer. I have narrowed it down to three. Is this from my Welsummer, Black Copper Marans or the Cuckoo Marans . The Welsummer has the darkest reddest comb, I have seen the Cuckoo Marans in the nest box a few times and the Black Copper is the largest of the thee. I know it is definitely not from my Red Laced Wynadotte or the Americana. So who done it??
