Old thread, forum is posting "other posts" that are old. But thought this was important, bc everything says they are monogamous which can be misleading if someone is expecting eggs/hatchlings from a certain pair and wonder why their lavender "pair" hatched a gray, or receive eggs said to be from such a pair.I will agree that some hens can act monogamous and if you have a male that seems so, that is the exception and not the rule. With equal numbers of males and females, I have watched males breed other hens than their mate and have seen dominant males take multiple hens leaving non-dominant males without a mate.
In the spring the females appear to choose their mates but later on dominant males will take other hens away from their chosen mate.
