My Bresse rooster is annoyingly loud. I use a inch and a half velcro. I wrap a 7 inch strip around a one inch pvc coupling and mark it with white out. I use the line as a guide, the velcro is slightly past the line, its tight. This interrupts his crow, so its muffled.
I plan on crossing my Bresse rooster with a standard cornish. The person selling the white cornish eggs on ebay pointed out that his roosters hardly crow. I hoping to get white pea comb chickens with blue legs.
I still waiting on the eggs, but I already have two dark cornish rooster chicks that I will experiment on first.
The Bresse chickens mature faster than Plymouth rocks, so I may be able to produce some hybrid meat chickens.
I currently have 10 eggs from my White Bresse rooster crossed with my black Jersey Giant hen in my incubator. I just candled them, they 100% fertile.
