Hi there! One of my hens who is a few months over a year, mounted one of my 22 week pullets. My cockerel, who is the same age as the pullets pushed her off and proceeded to mount the pullet himself. The hen (a RIR) then aggressively grabbed him by his comb and pulled HIM off. What is going on here??? I've heard of hens behaving more like roosters as they get older (like, 6-7 years?) but never at this age. She's laying eggs great. Thanks!
