I have an EE named Blue who tries to crow. In olden times my grandfather would say it was bad luck to have a hen crow (hahahaha) but its funny nonetheless. Do not know what makes then crow.......but your Hen is adorable!
What got me started is a friend of mine gave me a book yesterday. It has examples of all the breeds and pictures of the male and female of each. Well Lizzie looks just like the picture of the australorp rooster!!!
