First pic is my EE hen with her adopted Royal Palm poults. Second pic is the smallest RP poult (Yankee) that hopped on the largest poult (in the first pic), grabbed her by the back of the head and attempted to mate with her. I'm assuming the largest one is female. Two days later my 9-week-old bantam OEG rooster attempted the same. Aren't they a little young for this behavior?
