Other than that they don't seem overly interested or aggressive towards each other.
I moved my trash bins out of my garage to the outdoor patio and quickly learned that was mistake. I came home to find a hole chewed in the plastic bin and the black oil sunflower seeds rummaged through. Likely a squirrel.
The goats were hanging out on the patio so I also had to build a cedar fence to keep them out.

Predators in North Dallas haven't been an issue even with the addition of goats especially since my fence has no gaps or spaces to speak of. I also suspect now with the goats they'd have a run for their money.
