I hope someone can answer a question. We had two laying Isa Browns. They were free range and always together. One just got killed by a feral cat. Now the behaviour of the survivor has changed. (I see more than that, but I'll hold off on details lest I should be considered daft.) It seems we need to get her another companion. Now we wonder if the companion(s) should be an adult bird or chick(s). Which would be most readily accepted? The birds will then be kept in a more secure, enclosed area where they can still scratch around.
