Hi chicken lovers! I have nearly finished my coop just 2 sides and finishing touches to go on, however I am now at the stage of wanting to install a fence, What breeds will not be able to jump high? I think I will have to clip the wings to be able to lower the fence height unfortunately. Another question is, I have been recommended to get a high bred Sussex chicken (Originally I wanted Sussex Chickens) the reason being they are more hardy to disease and better layers. would this be correct?
