Our first priority is structural correctness and soundness.  Feet, legs, dimension, strong top-line and moderate frame are paramount when we design Big Prairie ewes and rams. 

"When we were in the market for Polypay ewe lambs, Mark educated us about the breed and delivered exactly what he promised; excellent quality and healthy stock.  Big Prairie is dedicated to their clients and the sheep industry."

Big Prairie Polypays is located near Ashton, Illinois.  We currently run 60 registered Polypay ewes and have marketed commercial breeding stock to 25 different states. Big Prairie Polypays started 15 years ago when our oldest daughter wanted to raise sheep for an FFA and 4-H project.  We originally purchased four ewes from Dr. Chet Palmer of Malta, Illinois.  Most of our stock goes back to the original ewes we bought from Dr. Palmer. Over the years we have enjoyed success, made many new friends and have thoroughly enjoyed raising Polypay genetics! Thanks again for visiting our site.  If we can be of service, please let us know. 

Big Prairie "Thank You"



 NSIP & Actual

Here at Big Prairie Polypays, we believe in the art of livestock selection and the implementation of technology.  Our philosophy is simple; breed Polypay sheep that are phenotypically correct and genetically sound.  We utilize technology in selection, but structural correctness is still a priority.  If a sheep can't deliver it's genetics because it's not sound or correct in its design, then it serves little purpose.  Big Prairie Polypay strives to be the intersection of phenotype and production as we build brood ewes.  As you search for genetics, please let us know if we can be of service.  We'd like to learn about your operation and share our passion for the sheep industry!
