My EE rooster is 11wks. old , he crows great , he`s a looker, best of the 3.The other 2 roo`s do not back down from him at all.He likes to grab the girls(12) by the neck and they squeal like a pig.(he is not trying to mount them).The other 2 get along great with girls.(they are all the same age).Is this the norm or should I~~~ YOU KNOW ???
