I have an order coming in may, and I requested two roos for each breed (except buff orpingtons, they weren't offerering those sexed) and I'm wondering if I really only need one. Could I safely breed off just one rooster and be able to replenish my flock? Or would it be a good idea to have two of each, especially since I'm going to be wanting to sell hatching eggs and chicks???? Also, how does linebreeding work if I have one roo and if I have two??? Thanks!!!
