Due to a coyote family in the area, we are down to ONE Australorp, down from ten EEs, Wyandottes, and Australorps.
We've done our best to protect Hildy from the coyote family, hence, she's been sleeping in our youngest daughter's room at night in a large dog crate.
She knows her name, comes when called, responds with a buk-buk or trill when called, and waits until outside to drop her 'marshmallows'.
She's escaped from coyote attacks three times (downside of free ranging) with all but a few tail feathers intact. Through these attacks, she's continued to lay 4-6 days a week!
All of our Australorps have been friendly, social girls, unlike the Wyandottes, who were just plain bullies.
Nothing is more entertaining than watching the backside of an Australorp when running (oh, that waddle!), lol.
We've only had three different breeds, so my opinion is limited; but I wholeheartedly recommend Australorps for anyone considering chickens.
