Hopefully, McMurray has switched up their breeding with the Dels since I had mine a few years ago. My friend, Kate, had a McMurray pair. She gave me hatching eggs from them. When they were a few weeks old, I sold them, male and female, because they were aggressive and flighty. Then she ended up culling both the hen and the rooster for aggression. That's why seriousbill had to convince me to hatch some from her stock, promising these would be very different. Of course, they were like a completely different breed, what a Delaware should be. That was about three years ago, so they probably aren't breeding that same aggressive strain now.
