I just discovered today that my big lead hen, a huge light Brahma has been tormenting my broody hens when they are sitting on their nests! This big Brahma will peck at the broody until she finally gets up and leaves the nest. Big Brahma then usually sits on the nest and lays an egg of her own, or will eat one of the broodies eggs! Its really messing things up! And my poor broody gets really upset and sometimes kicks eggs out of the nest. All the eggs end up being layed at different times. Even marking the original eggs doesn't really help because they will sometimes all just disappear. Today I hid and watched this behavior first hand. The Brahma chased the broody off her nest. The broody switched nest boxes. I went in and moved her eggs to her new nest. Then the Brahma comes over and chases her off of that nest and eats one of the eggs! I have plenty of nesting boxes for all of my laying hens, so I don't understand why she is doing this. I'm really shocked because I never would have suspected behavior like this. Why is she doing this?
