I have a 6month old Sweet Silkie rooster who loves his little flock of five 4mo old babies (sex is still undetermined). There are Never any issues! He even "Puts" them to bed in their coop before he goes to his coop (in the same pen) to bed!! A couple of weeks ago I bought a little pullet just a little older than the others. She fits right in! Last week I bought an older laying Silkie hen, and after the trouble started!! There are no issues with the younger ones... they just respect her, and she is not aggressive unless they cross that "invisible" line that only chickens can see, and then it's just a light peck. Well, my Rooster and the new hen immediately began fighting, which quickly turned into abuse by the Roo!! The little hen no longer has feathers in the middle of her head! DH and I have decided that "Buddy"Roo is trying to figure out how to breed her, but he is horribly rough, and she spends what little time I let them be together now hiding wherever she can wedge herself into, and he stays right there trying to get her out! Everybody says let them work it out, but I'm no Newbie to animals in general, and Buddy Roo is obsessed with this hen, and she will not survive if I let it continue. Today I have Little Hen in the adjoining pen by herself, and she is happy, the little flock has finally relaxed, and Buddy Roo is calm. My Question is: Will things ever change?? When Buddy Roo grows up and becomes more sexually mature, will he be less rough? His present behavior is totally unacceptable! Please give me your input! He is so sweet to me and his little flock, and I don't want to have to part with him, but hen abuse just won't do!! Will it get better?????
