I have 23 week old Amberlinks and 11-13 week old Bantam Brahma and Brahma/Silkie crosses. The other day I had 2 of the younger ones out for a little free range (supervised!). Well on of the Amberlinks, Vilma was out too. She ran right up to the little one and grabbed her by the back of the neck..... This is also the same hen who ran up and bit me. This was either for taking the eggs from the nest or petting one of her sisters. Is this normal????
