Hmm. Our SLW roos have been docile and sweet, and they even get along with our Buff Orp roo. Go figure.
Wait a few more weeks and see what literally develops. If you end up with a bunch of roos, you could always post notices on Craigslist and at your local farmers supply or feed store instead of culling them. Surely someone near you might want one for breeding or for flock protection...
