Hello, I have 2 Bantams that I hatched in late August. They are in the chicken coop. When they were 3 weeks old I hatched 12 orphaned Guinea Hens and the Bantams accepted them like siblings. I hatched 6 Silkies last week and I brought them into the shed the other day to "introduce them". The Bantams didn't take any interest in them what-so-ever. A couple days ago I brought one of the Silkies to the coop and put it in the brooding box. My Mille de Fluer looked in the box and walked away. I thought she doesn't even care...then she attacked me! She was behind me, I was sitting on a stool and she flew up on my back and was pecking me and flapping her wings. I took my baby and left. Yesterday I went into the coop to feed them and she was hissing at me...what's up with that?? Now I'm afraid to put my 6 Silkie chicks in there with them. What should I do?
