I had 5 hens and I just introduced a roo Saturday afternoon. My family and I went out to eat that evening and a couple of hours later when we came home, my dog had killed the rooster. I was so shocked and upset! I'm not sure why he killed the rooster unless he was causing a ruckus with the hens and my dog thought he might be hurting them? Anyway, I've been trying to read on how long sperm travels and eggs form, etc.....and I need to know if I'm right or not. From what I've read, I figure that if there's any chance of fertile eggs, they will be layed next Saturday or later? Also, any input on my dog and how to prevent him from killing roosters would be appreciated. Thanks!
