We added 7 hens to our small flock in August. We mixed it up - 2 light brahmas, 2 eggers, 1 buff Orpington and 2 barred rocks. This week, I've gotten some oddball eggs that I think MUST be from the "youngers." I have 2 eggs that are half sized and 1 "dud" with a full yolk but soft shell. These hens are probably 18 -19 weeks old. My first hens were all silver wyandottes and they took 24 weeks to lay. I'm really excited about these eggs! I suspect it is the eggers, because I saw one lingering in the coop. How early have you had hens lay? Which of these breeds would you suspect? Merry Christmas!
