Well my chickens were completely free range in my back yard, but liked to sleep on my porch. So I put a light in the coop and cooped them up for a week and they have been succesfully retrained to sleep in the coop. However, while they were in prison I put up a fence around the coop and opened up the pasture behind my back yard so that they would have that area and stay out of the yard....So now they have decided they want to jump the fence every chance they get when this was never an issue before. They would occasionally hop the fence into my front yard but not a big deal, now they are hoping the fence into my neighbors yard thay borders ours and also jumping the fence into the horse pasture on the other side AND hopping over into my back yard still yet. Keeping them confined to just a small run isnt an option as I want them to be free range and I'd rather not clip their wings if I can avoid it but I cant think of any other options so Im looking for advice. I just cant understand WHY theyve decided to hop the fence now as theyve never done it before and the pasture they now have access to is much bigger than my yard and even has a small stream in the lower part?
