My girls are all 11 months old this month. Little "Lonesome Dove" is the smallest and she's being picked on. She has always gone off on her own when they're free in the yard. But the poor girl's head and back of the neck are bald. I put some BLue Kote on it, so now she actually looks more like the others with her purple head...4 of them are maybe Lakenvelder crosses, so they are white with black heads and tails. So now that I've dosed her with blue kote do I have to separate her from the flock at night too? I feel so bad for her. I don't think they're pecking at her anymore. Help?
