Mine started laying a couple days before 19 weeks of age, which in my opinion is pretty good. That last of my NN pullets, which was actually a mixed breed NN and probably Cochin, to start laying began between 20 & 21 weeks. After a month of consistent laying their eggs weigh on average about 1.45 ounces. (Yes....I even weigh their eggs daily.)![]()
Too many folks judge an egg by it's overall size but it's the weight that tells the REAL story.
