I am not at home right now, so I can't help my mother, but I was wondering if any of you can.. Yesterday she noticed two of our hens, almost 6 y/o Australorp, Inky, and Speckled Sussex, Huevo, had bare bums. We didn't think much of it since the Australorp would do that to herself in the past either to cool off or prevent poo from sticking. Today, the Australorp's bum is bloody. Sussex is fine. Inky panting (it's not that hot out), doesn't want to go outside, and is not afraid of people like she usually is. There isn't any bloody poop around the cage. Our 1 y/o polish Einstein's 'fro is bloody so we are afraid she's bullying them or making the bleeding worse. If we were to remove someone from the coop, do we remove the bloody australorp or the supposed culprit? Any advice I can give to my mother?
