I know hens squat to let a rooster mate with them. What does it mean when they sqaut when I aproch. Do they think I'm a rooster. Normally it's just the tamer hens but I also have a few that run away from me but will sqaut if I chase them, or they didn't realize I was there. Does this mean they're afraid of me? Is it okay to pick them up when they are squating? I don't have a rooster.
