Vita I had to train all of the dogs to be on their best behaviors around baby birds. I did take each dog (usually with BF as helper) to the room where the brooder was to show each bird to each dog. I picked the birds up and held them close to me so the dogs would understand they were important and BF held them on leash, had them sitting and could control things if anyone got too excited. It has worked out well. Lily doesn't care about the chickens just wants to eat their food which is organic but corn based and off her list of things to eat. Peeves finally has gotten old enough to not try to herd them anymore. He made friends with one who has since passed on. We showed him her body so he could hopefully understand she was gone from his life. Javelin is still willing to harass them a bit but also has such a rock solid recall that I can call him away from them.
Floofy I made sure I watched when they played like that but I rarely intervened when Javelin was young and I still don't.
