@Tarsius, Yes I think it was the (now deceased) female. She did have really impressive horns. The first broad one from her was turning ontward a bit bend... The second on front was larger and green regular.
Unfortunately at some point both cow Tsororo and bull Kalusho were both dehorned and all that beautiful natural keratin crop on the tip of their heads was seriously ... (damaged beyond repair for very valid reasons ...).
