There is a reason for higher asking prices by quality purebred breeders which is they sell proven HIGH QUALITY animals that will produce quaIity offsping. I know that you understand the garbage in = garbage out principal especially in genetic quality. So, buy fewer breeding stock and they will be more PROFITABLE than the poor foundation stock. Also, the RAM is equal to 1/2 of your flock, so buy the BEST qulity genetics that you can find. Google Dorper sheep to get ideas of the breed standard to achieve in your flock.
