I have 10 chickens, 3 lavenders, 1 warren, 2 Marans, 2 Light Sussex 2 Spotted Lady's i have a x large coop and they are free range so have loads of space . All my hens are picking on one of my lavenders so much so that's she scared to eat and drink and hides in the coop or up on high branch.I have been using the pecking spray and that has helped with the other birds. I have been watching them and now have taken the two who i think are the main bullies and all SEEMS a bit better tonight. I am going to introduce the two main bullies back tonight into the coop and hoping this might help with a new pecking order.If this doesn't work does anyone have anymore ideas on what i can do to stop this. Any help will be great.
