I currently have 10 hens. I am going to get about 4 more pullets and I want to get a rooster this time too. How many do I need to guarentee fertile eggs. So /I will have a total of 14 hens...I was thinking 2 rooster and my hubby says nope,j ust one. Will there be a problem with having 2 roosters? Will they fight? What breed is more docile for roosters?
