I have a Black Australorp with the same issue. Scratching my head. No answers/fix here...just empathy. Been at least a month. My understanding was that they're super good layers. Mine is 10 months old in a mixed flock of 10. None are the same breed. However, I do have a Black Copper Maran.Any update? Having the same issue here and trying to figure out why!
Hopefully, someone out there can help us all.
