Hello! Almost a week ago we put our 3 Welsummers (2 might be roos, jury's still out) and our lone Cuckoo Maran in the coop. They've just turned 17 weeks old and to celebrate the occasion one of them laid their first egg! We found this little guy in the nesting box with all of the eggs from our big girls yesterday. What's the consensus, Cuckoo egg or Welsummer egg? I'm thinking Welsummer. Wyandotte egg, Ameraucana egg and our mystery egg.
