Am first time chicken owner and have got a coronation , light Sussex and a orph buffing ton . I originally had the coronation and light Sussex, but light Sussex was killed by a dog we had only had them for a few days. So I got 2 more chickens another light Sussex and the orph buffing on the two new ones get on well and the coronation and Sussex get on fine but coronation is pecking around the eyes on the orph buffing ton. What can I do to stop this? Please help.
