There are a few members who have or have had pet birds with no problems. They were raised together. Mine chases rabbits, squirrels, and birds. No bird had better land in her yard. They are terriers, so it is a natural behavior for them. I hope you can get some good advice, but I don't know how you can change what they most likely have learned over the years. I would just keep the bird in the cage and keep them separated. If they are like mine, they have been used to chasing birds from their yard. You can try to correct them whenever they show bad behavior toward the bird, but I don't know if you can ever completely change it.

As far as the Advantix is concerned, has it been applied to them in the past? Some are more sensitive to some brands than others. I use the same thing on mine with no problem. Have you discussed this with your vet? Perhaps another brand would not be so harsh to them.
