Hello! As the title says I have a couple of questions about my chickens. First my rooster is starting to try to mate the girls and my dad said that if he continue to do this then we would sell him. So is there any way to sterilize a rooster? My second question is when do hens stop laying? My girls just started but I'm just wondering when they stop that way I am prepared. Okay my last question is what color are the eggs of Americana's, Amber Whites, Cochin's, and New Jersey Giants?
