I have one, possibly 2 austrolorpes sitting on a clutch of 12 eggs, due to hatch on the 30th. All, but possibly 2 are doing great, not sure about the other 2. These will be mixed from my own flock. I love watching these hens, (if these are the same 2, they coparented 4 chicks last year) take care of their chicks. I'm gonna check tomorrow, because I think one of them just went broody, and if so, I'm gonna pull her to sit on her own clutch.
