I have 3 pair of Hamburgs . THe roos will be very protective killing animals that will hurt your hens and steal your eggs. Your hens may loose some featers, but their much better off with roosters to protect them. YoYo, I find that really hard to swallow right now. The roosters were not protecting anything but themselves.
Roosters are more for show and fertilization use only.
They do cackle when they find something of interest but thats about it. At this moment I am still upset over the fact that I lost so many to this coon, he was feeding well as when he was killed he weighed in at 17 pounds. You are being pig headed to think that roosters don't do anything. Your roo probebly did try to do something for his hens, but what can you expect a roo to do whith a coon. My freind's roo almost got himself killed protecting his hens from a rotwieler.
