I've got a 5 month old Cuckoo Maran Rooster who just started crowing. He has been living with 9 -1.8 year old EE hens and 1 - 7 month old Polish (think a hen...but still uncertain...not crowing or laying yet). We separated the two about a month ago...put the Polish in with the 3 month olds. EVERY time we let Polish out to range...CUCKOO roo GUNS for her. I mean he charges her and chases her around grabbing the back of her neck and pecking her. NOW...I know what the neck grabbing is for....but why would he GUN for her. I mean he literally looks like a BULL charging...scratching the ground before he takes off head low to the ground. I've been grabbing him...hanging him upside down...and he calms down. BUT still he keeps charging poor Polish. My question is SHOULD I just let him at her? See what happens? Or should I keep stopping the behavior?
