He is a young roo but all of my chickens are under a year old. Big Red (she hatched in February so the oldest biggest hen I have) takes no notice of him at all. I put him in a pen in the shed by himself for the day. He is a little bantam Cochin. Do you think Big Red could set him straight? she is a huge Rhode Island Red (hatchery, almost as big a a jersey giant, no one else is that big, I thought she was a male till she started laying)
