Finally got our first egg. I am pretty sure it was the larger of the Buff Orpingtons because of its behavior. But the Black Australorps are older, so who knows? The egg was medium sized (on the small side of medium), but perfectly shaped with a nice light brown color. We cracked it open (nice hard shell), fried it up and ate it. Good color on the yolk and a nice firm white. Just for the record, the Orps are 22.5 weeks, and the Australorps are almost a week older.
