I picked up four day-old Buff Orpingtons from the feed store yesterday. They are 96% guaranteed to be females. But I'm noticing lots of chest bumping going on and when I put my hand inside the brooder, one will run up and peck me. These ladies are just days old. Not even a week. Do I have a roo? I bought four from this place last year and one turned out to be a roo. I really only plan on keeping two of the pullets so even if two are males, I'm still okay. But I was hoping to sell the two others as pullets. Really breaks my heart to give away roosters because I know what their fate will probably be. Thoughts?
