Good point.What does the maternity ward look like?
I'm very partial to my Australorp. She's like yours and is rock steady and an EXCELLENT mother.
I had a nutty biter and I broke her. I had another that went a bit too far and tried to flog my face when I reached in to grab the baby bottle. THAT'S not happening.
I personally think that the ones that aren't nutso about defending the nest from YOU are thinkers and make better mothers and will be easier for you to manage during the incubation. That's my 2 or 3 or 4 cents. I kinda lost track on how many cents I put in...
