I added 3 BOs to my flock this year,well your eggs look like 1 of my girls eggs. She started laying at 20 wks which I thought was kind of early for a BO but whatever she is laying albiet small eggs kind of the size of a banty. My other 2 started 26 and 28wks respectively. That being said their eggs were significantly larger that the first ones and still are today. All of them egg size has increased. That first girl started 9/3 and layed for 42 days straight just small ones. If I were to grade them it might be now a medium egg as to where her sisters are large.
