We have a mystery on our hands as to who is laying here! Our girls are just 20 weeks old, but our Speckled Sussex started laying at 18 weeks. Our Sexlink at 19 weeks. We know which are the SS eggs (the small ones in this photo) and the SL (the one at 11 o clock in the photo). However, we don't know about the speckled egg or the dark one at 6 o clock. They look like they are from different chickens, but are they? We have a Buckeye, Salmon Faverolle, Silver Laced Wyandotte, Speckled Sussex, and Red Sexlink. Thoughts?
