I have a large Cochin roo that seems to have taken a real shine (if you know what I mean) to my little silkie bantam. She now stays hidden most of the time or stays in the coop and won't come out. The roo is still young and does not have spurs yet. But I still worry that he is just to big and heavy to "pick" on this little hen all the time. I have 20 other larger hens in there so why does he like this one? I'm afraid he is eventually going to really hurt her. Is he too big/heavy? Will it alter the size of her eggs? Will he ever leave her alone and choose the bigger girls?
