Hi there...know that there are lots of things to read on this...and I've read some but, wanted to get opinions for my specific situation. Have a small flock, 2 year old NH, 6 mos bantum brahma, 6 mos old bantum wyandot, three 10 week old red star, a 5 month old silkie rooster, and two 9 week old ish silkie crosses...and have had the flock for about a month. We have a 50/50 cross dog bout 3 years old, shephard and rottie. She is a big dog...but a good dog. She is not mean and gets along well with our cats (actually, one of our cats loves to beat on her...she tolerates it and may chase him a bit...but, it can be funny to watch). Her only issue is that she wants to jump on people when they come in; not to be mean but because she is SO excited! We are trying to break her of this...and she is getting better but...Anyway, she WANTS those chickens...when the chickens free range around our house, she will run from window to window to window to watch...she will jump up on the door and windows to watch. She gets very excited...we have taken her on the leash and by holding the collar out to see them...ONLY, at this point, when they are in their run. If let go of...she will run around the run really fast and excited. Yes, it appears like hurding behavior but...hubby tried to "introduce" her with them outside the run...not funny. She was not barkey, growley...she just wanted to pounce and jump on them. We don't trust that she wouldn't hurt them...maybe not on purpose but still. We aren't sure she will ever get out of this behavior and be able to just be around them. If she is out on her run...and they are free ranging (they don't get that close, they haven't discoverd that far from their run yet...but I know they will)...she almost chokes herself with excitement to get to them. Help! We don't want them separated forever...it's kinda stressful.
