My husband and I went to a lot of trouble building a fenced area for the chickens...and they just fly right over it. Now they're flying over the larger fence (about 4' tall) into the dog pen. When I first saw them there a few days ago, I nearly had a heart attack. I was SURE that my dogs (2 retrievers) would kill the chickens if given a chance. But the chickens were alive and well! I couldn't believe it!!! I still don't want them in there, but it seems like I can't really do anything about it now. As I type this, all three of them are running around in the heavy rain even though I opened the door to my greenhouse and put some food in there so they'd have shelter besides their coop. I guess they're not bothered by getting wet?
