LORDY! Good luck with that little schnauzer!
My dogs don't have that kind of temperment, but what I did was when I got my chicks home, I would hold them, and show the dogs, even let the chicks give the dogs kisses.. With plenty of supervision of course...
My big dog got a hold of our roo once, and she got in B I G trouble.. Now when the chickens get out.. the dogs just stare at them... It takes awhile for them to get used to because thier nature is to eat em up! :}
