I have a couple of these birds and aside from their lovely coloring, they're a very sweet-natured bird. They're awesome foragers, yet come RUNNING when I go out and yell "girrrrlies...." They follow me all over the backyard (but then again, so do my cuckoo marans). They get along great with my 3 cuckoos. I have seen no aggressive behavior at all with them. One of them insists on laying in the rose bushes, but at least I know where to look. Very happy with these birds and would recommend them to anyone. How can you lose? Good looks, good personalities and respectable egg layer too. Yes, I do have to be careful or one of them will follow me into the house-she's a pest at times
