So the confusion continues from when they were chicks. We thought we got 2 bantam EE, 3 OE, 1 Chocolate Orp, and 1 Black Australorp. We added a Golden Comet when we found out that the EEs were bantams.
We have been thinking that the CO was actually the BA because the supposed BA got feathered...
We had a mixup with our chicks, but we think this hen is most likely a Black Australorp. Definitely not the Chocolate Orpington we thought we picked up! Hope this helps 🤷♀️
