I have read about crowing hens but found it hard to believe. We have 3 australorp/polish hens that are almost 3 months old. Yesterday I heard a strange noise out the front door and saw one of them making obvious crowing sounds. We already have 4 roosters and all the chickens are free range. Thus ruling out the need for one of the hens to become dominate and take on rooster characteristics! All three hens look identical and none of them have other rooster-like attributes. I am just curious what is going on with them!!
