As I integrate my 3 Hooligans I am finding the pecking order remains the same and the new girls slot in at the bottom.You are correct. They have settled a lot. It seems that Phyllis is a full member of the tribe again. Between being allowed to roost in the coop and everyone supporting her hatching attempt. These are dramatic changes in her status.
Of course at some point in will be adding 3 more. I'm certain they will fire up again.
I locked them out of the hen house part of the Chicken Palace because I needed to do some work there to extend some brackets for the Hooligans roost (it was too near the wall) and it was harder to do than expected so they were not happy. They sat outside the door yelling at me (go out in the field and find grubs you silly chickens!).
When I eventually re-opened the chicken door they hilariously marched in with perfect spacing between them and exactly in the right pecking order. Military precision!
Then Bernadette messed it up by deciding the Hooligans were going to go out and play after all.
