Okay, I have a 15 year old catahoula dog. She has always been such a great dog, but lately has been killing pigeons and squirrels more and more! I'm scared that when I build my chicks coop and finally move them out that she will get them! Who has dogs they were unsure of? How did you introduce them to your flock? What was the outcome? Any losses? I want them to free range my backyard during the day (yes, I'm a city girl). Any tips? Ideas? Thanks!
