Hawkeye-Your Zorro might try to breed another male, but I can't imagine that any self-respecting rooster would let him do that to them.
Glad you found a good vet. It sounds like it hit Zorro pretty hard. It's hard to say if it was something dormant or just something they caught along the way, but it sounds like you are on your way to being a good chicken vet yourself. I'm sure it's not how you wanted to learn, though.
I would NOT give them a bath right now. It might be pretty stressful for them. Wait until they are pretty much over this before you do, especially if they have not been bathed before. They really do relax and enjoy it after they realize you are not going to boil them alive or something. Nevertheless, I think it does stress them a bit, and then there is the matter of keeping warm and getting dry.
Trish-I agree with Chicken Danz. It is hard to tell how the pup will react if the rooster is allowed to keep beating up on her. I would want them to be in with chickens they can cuddle up to and be comfortable with. If they are afraid or the rooster continues to be aggressive it is hard to tell if she might decide that the chicken is a "foe" rather than "friend." I wouldn't worry about Jasmine being more timid. They are such cautious, wary dogs. I think it's a good indicator of their natural instincts.
I've watched my dogs get head butted, stepped on and generally abused by our goats. It doesn't bother them a bit, however, they are adult dogs. When we get another dog I intend to put it right in with some of our baby goats and some chickens so they get aquainted right away. Oh, yes. I agree with the leash training, too. Just think what it's like getting a 100 lb dog into a car and to the vet for treatment or neutering when you can't even get a leash on them. It ain't easy, I can tell you first hand. They seem to naturally fight a leash more than any other dog I've had, so start early and frequently to get them used to it.
Checoukan-your text message totally confused me. My roosters all walk whichever way they please. As I said, if they were smart they'd be walking south for the winter, though.
The cast iron rooster doesn't walk at all. He just hangs there.... but he FACES right.
