I have a silver-laced wyandotte, cuckoo maran, and auracauna. I collected my very first egg last week (far right, and yes, I blew out the egg so that I could keep the shell. I was just sooo proud of my first ever "home grown" egg!), and the other three I collected over the weekend. Is the darker brown egg from my maran? or just a different shade from my wyandotte?
