I have two Pekin drakes,one I believe is part jumbo,or is jumbo,and use to be the most attractive guy in town,had all the ladies following him,quacking for him etc.2015 spring I got two ducklings,one turned out to be a drake.He was punished,raped,bitten it was TERRIBLE.His mate was also raped at least 66 times a day. Well,after about 6 months of age they were successfully accepted into the flock (But still had been shewed occasionally.)Well after those few months of being with the flock,the drake begin fighting,not for position,I think for ladies,because its 2016 now and were on to summer now,it has gotta stop,a year fighting.They cannot mate in front each other,hens can hardly favor just one male,otherwise they begin blocking one another from her,or they punish each others mates.This got even worse when the young drakes mate got killed,he really didn't have anybody to flirt with,mate with or anything.So,he continue to compete.After about 7 or 8 months he realized he could only win a few fights,and now it's just a fight occasionally that only last a few seconds,either that or he'll be able to run the drake off from mating (They bicker back and forth on that chasing each other off).The younger drake stands no chance against Jumbo man.His chest was bare from fighting all the drakes in the yard (We got rid of the three mean wardens.)He rarely faught The Wardens because they were just a bunch tough outsiders who had each others back,and could rape anybody they felt the need to. Maybe I should get rid of someone or just get separate pens.
