Question about egg laying signs for those with Black Australorps

[alexa009]

My australorp started laying as early as 4.5 months. Chickens don't always do the egg squat either. I have had a brahma that has been laying for over 6 months now and has never done the egg squat before when I have picked her up, neither have my marans. The best way to tell a hen is ready to lay is fast growing comb and loud or odd behavior. You can check out my article if you like on chickens getting ready to lay.
