We have ordered 25 chicks thru 4H that are promised to be all female. Now 2 'old timers' have told our son that for them to really be good egg layers and for them to lay more eggs, he also needs to have at least one rooster in the bunch. I had not planned on a rooster due to the noise mostly, and because I am not ready to hatch chickens on my own. Yep, I am a newbie, and with no rooster I can guarantee no fertilized eggs. Now thogh my son is begging for a rooster or 2 as well. How much difference will having roosters make?
